Population data

Population data are taken from World Population Prospects 2012 (http://esa.un.org/unpd/wpp/unpp/panel_population.htm).

Single-year-of-age values were interpolated from population data in five-year age groups for the low-, high-, and constant-fertility variants.

Thumbnail graphs

Thumbnail graphs are used to select the country to be displayed in the upper panel and to compare profiles across countries.

Scale

Units: Values are expressed in US dollars. Per capita consumption and labor income estimates in local currency units available in NTA have been converted into US dollars using purchasing power parity conversion factors available from the World Development Indicators.

Proportions: Values are expressed as a percentage of the total for all age groups combined. For the per capita profile each value is calculated as a percentage of the total of per capita values summed across ages 0 to 100.

Previews

Preview options are used to compare different measures across countries using the thumbnail graphs. The values compared depend on the scale and fertility scenario selected. Proportions generally provide a better way of comparing countries that differ greatly in their size and/or level of development.

Per capita: Compares the per capita age profiles of labor income and consumption.

Population: Compares the age profiles of population.

Aggregate Totals: Compares the age profiles of total labor income and consumption at each age.

Fertility scenario

Constant: Total fertility rate is constant at the level estimated for 2005-2010.

Medium: Total fertility rates converge to low fertility in all countries based on statistical analysis described in World Population Prospects 2012 available on the Population Division website.

Low: Total fertility rate is lower by 0.5 births than the medium variant in all years.

High: Total fertility rate is higher by 0.5 births than the medium variant in all years.

National Transfer Account estimates

NTA per capita age profiles are constructed by single-years-of-age for a recent year and held constant at the base year value for all scenarios. The aggregate NTA age profiles are constructed by multiplying the per capita value at each age by the population at each age estimated/projected for 1950 to 2100.

Support ratio

The support ratio is calculated as the ratio of total labor income to total consumption calculated in each year using population estimates/projections for the selected fertility scenario and per capita age profiles of labor income and consumption held constant in the base year.

Labor income

The value of the work effort of resident employees, the self-employed and unpaid family workers. Labor income is measured by earnings, the value of employer-provided benefits and an estimate of labor’s share of income from unincorporated business.

Consumption

Goods and services consumed by residents including those produced by private sector (corporations, households and non-profit institutions serving households) and the public sector, such as publicly provided education and health care. Purely public and quasi-public goods are included.

Source

NTA estimates were constructed by country-level research teams following methods described in the United Nations, Department of Economic and Social Affairs, Population Division, 2013, National Transfer Accounts Manual: Measuring and Analysing the Generational Economy (New York: United Nations).
