Overview

Pension systems are designed to provide income for retired people who are no longer earning an income through employment. The UK pension system is made up of two distinct components: a mandatory state component and a voluntary private component. Private pensions in the UK are provided by employers in the private and public sectors and by insurance companies.

The statistics collected include:

  • membership of pension schemes

  • contributions made by members and employers

  • scheme assets and liabilities

  • income from pensions in retirement

  • estimates of saving for retirement

Technical Data

There are a variety of sources from which pensions data are collated. These include surveys and information from administrative records. Some of the key sources are listed below.

Annual Survey of Hours and Earnings (ASHE) - Office for National Statistics (ONS)

The ASHE provides information about the levels, distribution and make-up of earnings and hours paid for employees within industries, occupations and regions, and is based on a 1 per cent sample of individuals with National Insurance numbers in the UK. The ASHE pensions tables replace previous pensions analysis from the New Earnings Survey and present results for UK employees by type of pension arrangements within their employer. The tables contain membership breakdowns by scheme type, age, sex, contribution rate, industry, occupation, size of company and contracted-out status.


English Longitudinal Study of Ageing (ELSA) - Institute for Fiscal Studies (IFS)

The ELSA survey sample is drawn from a representative sample of respondents to the Health Survey for England (HSE) aged 50 and over. The Work and Pensions module collects from each member of the ELSA sample employment details, job characteristics, earnings, occupational pension contributions or receipts, and retirement decisions. The information on pensions collects sufficient information to establish individual pension contributions and pension rights for those not currently drawing pensions and to determine how these will change with employment or retirement decisions.

Expenditure and Food Survey (EFS) - Office for National Statistics (ONS) and Department for Environment, Food and Rural Affairs (DEFRA)

The EFS is a continuous survey of household expenditure, food consumption and income based on a sample of around 12,000 private households in Great Britain. The EFS began in 2001 taking over from the Family Expenditure Survey (FES) and the National Food Survey (NTS) and includes details of household expenditure on private pensions as well as the general expenditure of households in receipt of state pensions.

Family Resources Survey (FRS) - Department for Work and Pensions (DWP)

The FRS is a continuous survey of around 29,000 private UK households and collects information on both the receipt of pension income and whether contributions are currently being made (both occupational and personal pensions) as well as information about overall profile of scheme membership and information broken down into various categories (for example sex, age and employment). For occupational pensions the FRS contains information on length of membership, whether the scheme is contributory, whether additional voluntary contributions are being paid (and in what form), and what has happened to earlier accrued rights. For personal pensions it contains information on how many personal pensions are held (currently), when they were taken out, if contracted-out, who pays in and how much was contributed by the individual.

General Household Survey (GHS) - Office for National Statistics (ONS)

The GHS is an inter-departmental survey carried out by ONS collecting information on a range of topics from people living in around 13,000 private households in Great Britain. Results from the GHS include data on membership of personal and occupational pension schemes by various social characteristics (age, sex, FT/PT employment, earnings levels, socioeconomic classification, industry and size of establishment).

Households Below Average Income (HBAI) - Department of Work and Pensions (DWP)

Based on an analysis of the Family Resources Survey (FRS) the HBAI series presents information on potential living standards of pensioners as determined by their disposable income in a given year, changes in income patterns over time and income mobility.

MQ5 Business inquiry: Insurance Companies, Pension Funds and Trusts Investments - Office for National Statistics (ONS)

MQ5 is a quarterly ONS publication containing information on the activities of insurance companies, self-administered pension funds, investment trusts, unit trusts and property unit trusts. The estimates are derived from statistical enquiries to these financial institutions.

Occupational Pension Schemes Survey (OPSS) - Office for National Statistics (ONS)

The OPSS provides a detailed analysis of occupational pension provision in the UK. This includes the membership of schemes by scheme size and scheme type, the nature of the benefits provided and the level of contributions paid by both employers and employees. The sample is selected at random from a database of all UK based occupational and personal pension schemes with two or more members maintained by The Pensions Regulator (TPR).

Pensioners' Income Series - Department of Work and Pensions (DWP)

Contains estimates and interpretation of trends in the levels and sources of pensioners' incomes, based on two household surveys, the Family Resources Survey (FRS) and the Expenditure and Food Survey (EFS).

Pension Trends

Pension Trends is an online publication which draws together statistics from ONS, a number of government departments and other organisations to highlight the complex issues that shape trends in pension provision in the UK. It contains chapters on pensions legislation and reforms; the ageing population and the transition from work to retirement; state pensions; private pensions, including membership of pension schemes, pension contributions and scheme funding and investment; saving for retirement; pensioner income (from pensions and other sources) and expenditure; and pensions in the National Accounts. More information can be found on the National Statistics website.

Pensions Protection Fund (PPF) 7800 Index - Pensions Protection Fund (PPF)

This PPF monthly update provides the latest estimated funding position, on a Section 179 basis, of predominantly private sector defined benefit (DB) UK pension schemes.


Tabulation Tool - Department for Work and Pensions (DWP)

The Department for Work and Pensions now makes many of its statistics available for public use via an online tabulation tool. The statistics from the Work and Pensions Longitudinal Study (WPLS) are based on all claimants and cover information such as age and gender of claimant, duration of their spell on benefit and geographical locations of claimants.

The Purple Book - The Pensions Regulator (TPR) and the Pension Protection Fund (PPF)

TPR and the PPF produce jointly ‘The Purple Book’, a detailed assessment of the risks faced by defined benefit (DB) pension schemes, predominantly in the private sector in the UK. TPR also maintains a database of all UK based occupational and personal pension schemes with two or more members.

The State of the Nations Savings - Association of British Insurers (ABI)

Annual survey report based on the autumn quarter results of the ABI Pensions and Savings Index, an internet survey of savings behaviour conducted by YouGov of around 3,000 employed individuals in Great Britain. From an analysis of the State of the Nations Savings survey results.

Wealth and Assets Survey (WAS)

The WAS is a new survey that collects information about the economic wellbeing of households and individuals. Households in the survey are followed up to find out how their wealth varies over time. The survey includes pension provision and estimates of pension wealth. The report of the first wave (2006/08), ‘Wealth in Great Britain’, covers 31,000 households over a two-year period. More information can be found on the National Statistics website.

    The stage in people's lives when they are building up pensions. See also: Decumulation.

  • Active members

    Active members are current employees who would normally contribute (or have contributions made on their behalf) to an organisation’s pension scheme. In some cases, there may be a break in contributions, known as a contribution holiday.

  • Actuarial assumptions

    The assumptions made by actuaries in formulating valuations or making other calculations. Assumptions would include changes in longevity, wage growth, inflation, and the discount rate.

  • Actuarial reduction

    The reduction in pension, calculated by an actuary, that occurs if someone takes their pension before the normal pensionage specified in the scheme rules.

  • Actuary

    An adviser on financial questions involving probabilities relating to mortality and other contingencies.

  • A-Day

    On 6 April 2006 – ‘A-Day’ – the Government implemented a new, simplified tax regime for pensions to replace the eight existing regimes.

  • Additional state pension

    The generic name for the part of the state pension which is received by some people in addition to the Basic State Pension. Currently, it is the State Second Pension (S2P). Before 6 April 2002, it was known as the State Earnings - Related Pension Scheme (SERPS) and before that as graduated retirement benefit.

  • Additional voluntary contributions (AVCs)

    A pension top up arrangement where an employee pays additional amounts into a pension run by their employer in order to increase their pension entitlement. Normally, the contributions are deducted from the employee's pay. See also: Free-standing additional voluntary contribution.

  • Administrative data

    Data that are a by-product of the operational activity of an organisation, such as tax data from HM Revenue and Customs. Administrative data are distinct from survey data, which are collected specifically for a statistical or research purpose.

  • Alternatively secured pension (ASP)

    A form of income drawdown, introduced on A-Day to provide an alternative to using pension savings to buy an annuity.Individuals can continue to invest their pension savings and draw alimited income from their fund.

  • Annual management charge (AMC)

    A charge levied on an investment fund for its management and administration.

  • Annuity

    A financial instrument provided by an insurance company that pays a guaranteed annual income to the holder, typically until death. Members of defined-contribution pension schemes generally purchase annuities with their accrued funds upon retirement in order to secure an income.

  • Appropriate personal pension (APP)

    A type of personal pension that meets certain regulatory requirements that allow an individual employee to contract out of the State Second Pension (formerly SERPS) and receive contracted-out rebates from National Insurance payments.

  • Auto-enrolment/automatic enrolment

    The process whereby an individual is made a member of a pension scheme by default, and has to take action if he or she wishes to leave the scheme.

  • Basic State Pension (BSP)

    The Basic State Pension is weekly payment made by the Government to people who have reached State Pension Age. An individual's Basic State Pension depends on the number of qualifying years that they have earned during theirworking life. The number of qualifying years is based on the National Insurance contributions that a person has been paid, has been treated ashaving paid, or hasbeen credited with. For people reaching State Pension Ageon or after the6 April 2010, the requirement for a full Basic State Pensionis 30 qualifying years.The directgov website shows current levels of Basic State Pension (http://www.direct.gov.uk/en/Pensionsandretirementplanning/StatePension/DG_188551)

  • Beneficiary

    A term usually referring both to the member of a pension scheme and their dependants to whom benefits are payable. It is sometimes used to refer only to the dependants who will benefit.

  • Bond

    A negotiable loan instrument sold by firms (corporate bonds) and the Government (commonly known as Gilts), generally with a fixed term to maturity, that pays the holder the face value (or ‘principal’) upon redemption, together with 'coupon' payments paid semi-annually (although sometimes annually) during the term to maturity. A bond that makes no coupon payments is known as a zero-coupon bond.

  • Bulk buyout

    On winding up an occupational scheme, trustees will normally buy out the accrued benefits of members and other beneficiaries who have immediate or deferred annuities. Where there is a deficit in scheme funding, and scheme wind-up starts after 5 April 2005 and the employer is insolvent, the scheme will be assessed by the Pension Protection Fund.

  • Buy in/buy out

    With a pension buy out, existing pension scheme assets and liabilities are transferred to an insurance company. With a pension buy-in, the pension scheme sponsor exchanges the existing assets of the scheme for annuities that are provided by an insurance company. In both cases, the longevity risk of the scheme is transferred to an insurance company.

  • Career average revalued earnings (CARE) scheme

    A defined benefit scheme that gives individuals a pension based on salary times the accrual rate in each year of their working life. Entitlements that are built up each year are revalued until retirement in line with inflation or earnings.

  • Closed pension scheme

    See scheme status.

  • Cohort

    A group of people who are observed over time, usually defined by date of birth or date of attaining some other status. For example, a sample of people born in 1951 would form a birth cohort.

  • Cohort life expectancy

    See life expectancy.

  • Consumer Prices Index (CPI)

    The CPI measures the average change in prices (inflation) across a wide range of consumer purchases. It is the basis for the UK Government's inflation target which the Bank of England's Monetary Policy Committee is required to achieve. In June 2010, the Government announced its intention to use the CPI (instead of the Retail Prices Index) from 6 April 2011 for the indexation of state pensions and pensions for public sector employees, as well as of benefits and tax credits. Some private sector pension schemes may also use the CPI for indexation purposes in future.

  • Contract based pensions

    Pensions where the legal contract is between the individual and the pension provider, usually an insurance company. Contract-based pensions are also known as personal pensions.

  • Contracted out

    This refers to a statutory arrangement under which pension schemes that meet certain conditions may contract out of the State Second Pension (S2P), formerly the State Earnings-Related Pension Scheme (SERPS). The members’ and employers’ National Insurance contributions are reduced or partially rebated. Members of a contracted out pension scheme obtain rights to an additional state pension. See also: Minimum contribution.

  • Contracted-out mixed benefit scheme (COMBS)

    An occupational pension scheme which has separate defined benefit and defined contribution sections and which contracts out on both bases.

  • Contracted-out money purchase scheme (COMPS)

    A scheme that contracts out on a defined contribution basis.

  • Contracted-out rebate

    The amount by which the employer’s and employee’s National Insurance contributions are reduced when the employee is in a contracted-out occupational or personal pension.

  • Contracted-out salary-related scheme (COSRS)

    An occupational pension scheme that has retirement benefits that are based on salary, and which has been contracted out according to Section 9(2) of the Pensions Schemes Act 1993.

  • Contributions

    Payments into a pension by employees (and other individuals) or by employers.

  • Corporate bonds

    See bond.

  • Corporate securities

    See securities.

  • Crude birth rate

    The simplest overall measure of fertility in a population, given by the number of live births in a year per 1,000 mid-year population. It takes no account of the composition of the population, in particular the age and sex distribution.

  • Crude death rate

    The basic measure of the level of mortality in a population, defined as the total number of deaths per 1,000 mid-year population. The crude death rate takes no account of any variation in mortality levels by age or sex.

  • Decile

    See percentile.

  • Decumulation

    The drawing down of pension assets to fund retirement. In the UK it is permitted to access pension assets partially as a tax-free lump sum and partially as an income stream (i.e. as an annuity or income drawdown).

  • Deferred entitlement

    Entitlement to a pension payable some time in the future. It can be either entitlement to a pension payable from normal pension age for someone who has left a scheme or entitlement to a pension that has been deferred because retirement has been postponed beyond the normal pension age.

  • Deferred member

    A member of an occupational pension scheme who has accrued rights or assets in the scheme that will come into payment at normal pension age but who is no longer actively contributing (or having contributions paid on his or her behalf) into the scheme.

  • Defined benefit

    A pension in which the rules of the schemespecify the rate of benefits to be paid. The most common defined benefit scheme is a final salary scheme in which the benefits are based on the number of years of pensionable service, the accrual rate, and the finalsalary. An increasingly common alternative to the final salary scheme is theCareer Average Revalued Earnings (CARE) scheme which is also a defined benefit scheme.

  • Defined contribution scheme

    A pension scheme in which the benefits are determined by the contributions paid, the investment return on those contributions (less charges), and the type of annuity purchased upon retirement. It is also known as a money purchase scheme.

  • Dependant

    A person who depends financially on the pension scheme member, or did so at the time of the member’s death or retirement.

  • Dependency ratio

    The ratio of the number of dependent people to the number of those supporting them. For example, the old age dependency ratio is the number of people over State Pension Age in relation to the number of people of working age. The support ratio is the inverse of the dependency ratio, and is the number of people giving support in relation to the number of people depending on them.

  • Discount rate

    An rate used to reduce an amount of money at a date in the future (called a future value) to an equivalent value (called a present value) in the present.

  • Economically active

    People who are either in employment or unemployed. See also:Economically inactive.

  • Economically inactive

    Economically inactive people are those who are neither in employment nor unemployed, and who are not actively seeking work; these include people looking after a home or family, retirees and the long-term sick or disabled.

  • Employer-facilitated pension

    A workplacepension that is organised through the employer, enabling pension contributions to be made through the payroll. The employer may make a contribution. An employer-facilitated pension will bea group personal or group stakeholder pension rather than an occupational pension scheme.

  • Employer-provided pension

    A workplacepension that is organised through the employer, enabling pension contributions to be made through the payroll. The employer is likely to make a contribution. An employer-provided pension will bean occupational pension scheme, not a group personal or group stakeholder pension.

  • Employer-sponsored pension

    A workplace pension that is organised through the employer. It may be employer-facilitated or employer-provided.

  • Employment

    People who are in employment may be employees, self-employed, on a government-supported training programme, or unpaid family workers. The International Labour Organisation (ILO) defines people as being employed if they are in one or more hours of paid employment a week.

  • Equity

    A share or any other security representing an ownership interest, typically in a company.

  • Equity release

    Equity release schemes give home owners a way of accessing part or all of the value of their home, either as a lump sum or as an annuity, while continuing to have full residence rights during their lifetime.

  • Fertility rate

    The number of live births in a population in a given period. It can be measured in several ways. See also: Crude birth rate.

  • Final salary scheme

    See defined benefit scheme.

  • First tier

    See tier.

  • Free-standing additional voluntary contributions (FSAVCs)

    A pension top-up arrangement where an employee pays additional amounts into a pension provided by a company outside their place of employment to increase their pension entitlement. Normally payments are made from the individual's band account. Employers are not obliged to make contributions. See also: Additional voluntary contributions.

  • Frozen pension scheme

    See scheme status.

  • FRS17

    FRS17 is the accounting standard for UK pension costs. It is mainly concerned with defined benefit occupational schemes in the private sector but applies to all retirement benefits. It requires sponsoring employers to value on a “fair value” basis the assets and liabilities of their occupational schemes. The resulting surplus (or deficit) must then be recognised as an asset (or liability) in the company balance sheet. FRS17 replaced the previous standard SSAP24 on 30 November 2001.

  • Fund

    See pension fund.

  • Funded scheme

    A scheme in which benefits are met from a fund built up in advance from contributions and investment income.

  • Gilts

    An abbreviation for ‘gilt-edged securities’, also known as government bonds. These are negotiable loan instruments issued by the UK Government. They are generally similar in structure to corporate bonds, paying a fixed schedule of coupon payments together with the return of the principal (i.e., the face value of the bond) on the redemption date. Gilts are generally considered to be one of the safest forms of investment and so generate a correspondingly lower return than some more risky assets such as corporate bonds or equities. Some Gilts make payments that are fixed in cash terms, whereas others make index-linked payments.

  • Government securities

    See securities.

  • Graduated retirement benefit

    Between 1961 and 1975, employees paid graduated National Insurance contributions on top of their flat-rate contributions, above a certain earnings limit. Graduated retirement benefit is that part of an individual’s additional state pension that depends on these contributions.

  • Gross Domestic Product (GDP)

    The total value of economic activity in a country or region. It is measured in either current prices or real terms.

  • Gross operating surplus

    The value of businesses’ outputs, less intermediate inputs and the remuneration of labour.

  • Group Personal Pension (GPP)

    An arrangement made for the employees of a particular employer or groupof employersto participate in a personal pension on a group basis. This is a collecting arrangement only; the contract is between the individual and the pension provider, normallyan insurance company. See also: Personal pensions.

  • Group Self Invested Personal Pension (GSIPP)

    An arrangement made for the employees of a particular employer, or group of employers, to participate in a personal pension on a group basis. The GSIPP is similar to the Group Personal Pension except that it is the policy holder rather than the pension provider who chooses the investments. See also: Personal pensions.

  • Group stakeholder pension

    An arrangement made for the employees of a particular employer or groupof employersto participate in a stakeholder pension on a group basis. This is a collecting arrangement only; the contract is between the individual and the pension provider, normallyan insurance company. See also: Stakeholder pensions.

  • Guarantee Credit

    A means-tested benefit that is part of Pension Credit and provides pensioners with a minimum level of income.

  • Home Responsibilities Protection (HRP)

    This reduces the number of years for which someone has to make National Insurance contributions in order to receive a full state pension. It is available to people who are not in work because they care for children or the long-term sick or disabled.

  • Household head or reference person

    In the past, the 'head of household' was used in surveys to represent the household. This was defined as the eldest householder, with males taking precedence over females in the case of couples or non-related joint householders. However, since 2001, the Office for National Statistics has used the concept of 'household reference person' instead. This is defined as the person in whse name the accommodation is owned or rented. When there are joint householders, it is the person with the highest income; if their incomes are the same, then the older person is selected.

  • Household saving ratio

    The proportion of total household resources – the sum of all households’ gross disposable income plus equity gains from pension funds – that is left once their consumption expenditure has been deducted.

  • Housing Benefit

    A means-testedbenefit through which the UK Government helps qualifying individuals to meet rental payments. Qualification criteria include income, savings and personal circumstances.

  • Hybrid pension

    Aworkplacepensionthat offers members either a choice, or mixture, of defined-benefit and defined-contribution rights at retirement. If the scheme offers a choice, the benefit is calculated as the better of the two alternatives; each acts as an underpin for the other. For example, a typical hybrid arrangement offers a defined-contribution pension but is underpinned by a minimum defined benefit entitlement.

  • Incapacity benefit

    Benefit paid to people incapable of work due to ill health or disability and who have sufficient National Insurance contributions or became incapable of work in youth.

  • Income drawdown

    Where an individual does not buy an annuity with their pension pot but instead draws an income from the fund. See also: Alternatively secured pension, Unsecured pension.

  • Index-linked

    Bonds, Gilts, annuities and other financial products can be linked to an index such as the Retail Prices Index. The income and capital values of linked assets increase in line with that index.

  • Individual personal or stakeholder pension

    A personal pension or stakeholder pension taken out by an individual on their own initiative, as opposed to a group personal or group stakeholder pension which is facilitated by an employer. See also: Personal pension, Stakeholder pension.

  • Individual Savings Account (ISA)

    A regulated savings account available to most UK residents as a means of earning tax-free returns on a variety of assets, including cash, life insurance, stocks and shares. There are limits on the value of total investment in any one financial year. In April 1999, ISAs superseded Personal Equity Plans (PEPs), and Tax-Exempt Special Savings Accounts (TESSAs) which had been introduced in 1987 and 1991 respectively to encourage personal savings. PEPs and TESSAs also allowed tax-free income and interest to be earned. Since the introduction of ISAs, no new contributions to PEPs or TESSAs have been allowed.

  • Insurance-managed pension fund

    A type of self-administered pension fund where an insurance company acts as external investment manager, but ownership of the assets remains with the scheme. See also: Insured pension scheme.

  • Insured pension scheme

    An occupational pensionscheme in which the benefits are secured by insurance policies and the insurance company holds the scheme assets. See also:Insurance-managed pensionfund.

  • International Labour Organisation (ILO)

    A specialised agency of the United Nations, created to deal with labour issues.

  • Interpolation

    The calculation of new data points to fill in gaps within an existing set of known data points. For example, if an annual survey of employment had run from 1990 to 2005 but had been suspended for 2002, then an employment figure for 2002 could be interpolated by taking the average of the values for 2001 and 2003.

  • Interquartile range

    The difference between the first and third quartiles of a distribution (see percentiles), which gives a measure of the extent to which the data in a sample are dispersed around the median.

  • Invalidity benefit

    A benefit paid to people assessed as incapable of work, which was replaced by Incapacity benefit from 1995.

  • Investment trusts

    Companies that produce income by investing in the shares of a wide range of other companies.

  • Liabilities

    In the context of pensions, the benefits owed to members by a pension scheme.

  • Life expectancy

    Life expectancy at a given age is an estimate of the average number of years that someone of that age will live thereafter. It is calculated using age- and sex-specific mortality rates at that age, at that age plus a year, at that age plus two years, and so on. Period life expectancy is calculated using age-specific mortality rates for the period under consideration and makes no allowance for changes in age-specific mortality rates after that period. For example, a period life expectancy calculation for a man aged 50 in calendar year 2000 would use male mortality rates for age 50 in 2000, age 51 in 2000, age 52 in 2000 (and so on). Cohort life expectancy is calculated allowing for subsequent known or projected changes in age- and sex-specific mortality rates after that period. For example, a cohort life expectancy for a man aged 50 in 2000 would be calculated using male mortality rates for age 50 in 2000, age 51 in 2001, age 52 in 2002 (and so on). The cohort definition is the better measure of true life expectancy.

  • Lifestyle fund

    An investment fund that has an asset mix determined by the level of risk and return deemed appropriate for an individual investor according to their age. Funds aimed at younger investors consist mainly of higher risk (and higher return) assets such as equities, while funds aimed at investors closer to retirement consist mainly of lower risk (and lower return) assets such as bonds. As investors age, their pension pots are moved into funds with decreasing levels of risk.

  • Limited Price Indexation (LPI)

    LPI applies to pensions in payment relating to contributions made from April 1997. Under LPI, pensions had to be increased by 5 per cent per year or by the increase in the Retail Prices Index (RPI), whichever was less, until 2005, when the rate was changed to 2.5 per cent or RPI. In 2010, the government announced that indexation would, in future, be based on the Consumer Prices Index (CPI) rather than the RPI. This change affects public sector pensions and some private sector pensions.

  • Longevity risk

    The risk that a pension fund or insurance company may end up paying out more than anticipated if those to whom it has agreed to paya pension live longer than expected.

  • Longitudinal study/survey

    A research study or surveythat follows a group of individuals over a period of time.

  • Lower Earnings Limit

    For the purpose of calculating rights to the State Second Pension (S2P), employee contributions are treated as having been paid on earnings from the Lower Earnings Limit up to and including the Lower Earnings Threshold for National Insurance contributions. For current levels, see the HM Revenue and Customs website (www.hmrc.gov.uk/rates/nic.htm).

  • Lower Earnings Threshold

  • Means-tested benefits

    State benefits in which the amount paid depends on an individual's level of income and capital and other personal circumstances.

  • Median

    The median of a distribution is the value below which half of the data lie. For example, if the heights of nine people are placed in order, then the median is the fifth height listed because half of the people will have heights belowthis and half willhave heights above this.The median is a useful alternative to the mean when data are not evenly distributed. For example, when looking at income or wealth, it gives a better idea of the 'typical' person than the mean.

For example, if 10 people earn an average of 15,000 a year and 90 people earn 20,000 a year, the average earnings of the group of 100 people is clearly not the simple average of 15,000 and 20,000, which is 17,500. The weighted average of earnings must be calculated, by multiplying each value by the number of people to whom it applies, summing the multiplied values, and dividing the sum by the total number of cases.

  • Winding-up
