Age	Description
Children	The population is comprised of individuals below age 20.
Adults	The population is comprised of individuals over age 20.
All Ages	The population is comprised of individuals of all ages.

Population	Description
Female	The population looked at is comprised of female individuals only.
Male	The population looked at is comprised of male individuals only.
Individuals	The base unit is the individual (rather than the household). This is equivalent to assuming no sharing of resources within couples.
Equal-split adults	The base unit is the individual (rather than the household) but resources are split equally within couples.
Tax unit	The base unit is the tax unit defined by national fiscal administrations to measure personal income taxes.

Type	Description
Average	The annual income (or wealth) average within a given group percentile.
Shares	The income (or wealth) share held by a given group percentile.
Thresholds	The minimum income (or wealth) level required to belong to a given group percentile.

Group percentiles	Description
All	Does not separate the population based on the indicator in question (e.g. income or wealth)
Top 1%	Top 1% of the population based on the indicator in question (e.g. income or wealth)
Top 10%	Top 10% of the population based on the indicator in question (e.g. income or wealth)
Bottom 90%	Bottom 90% of the population based on the indicator in question (e.g. income or wealth)
Bottom 50%	Bottom 50% of the population based on the indicator in question (e.g. income or wealth)
...and so on...

Post-tax national income is the sum of primary incomes over all sectors (private and public), minus taxes.

The chart(s) below show(s) how the Post-tax national income has being distributed across sets of complementing (they add up to 100%) percentile groups. We have tried to show this data for as many years as possible, but you may find that in some cases the information is just not available for some percentiles.
