In 2010 half of the people in Mexico had incomes of less than USD 4 500. Half of the people in Luxembourg had incomes about eight times higher (, Panel A). Countries with low household income included countries in Southern Europe, Turkey and much of Eastern Europe, as well as two Latin American countries – Chile and Mexico. Those with higher household incomes included Norway and Switzerland.

The total fertility rate indicates the number of children an average woman would have if she were to experience the exact age-specific fertility throughout her life. Allowing for some mortality during infancy and childhood, the population is replaced at a total fertility rate of a little over two.

The migrant population represents a growing share of the total population. The share of foreign-born within the population increased in all OECD countries between 2001-11, with the exception of Estonia, Israel and Poland (, Panel A).

The number of adults in a household illustrates additional information about household composition and how people live together, while indicators on marriage and divorce reflect on adult partnership status.

The old age support rate is the ratio of the population who are economically active to older people who are more likely to be economically inactive. It thus provides an indicator of the number of active people who, potentially, are economically supporting inactive people. It also gives a broad indication of the age structure of the population. Changes in the old age support rate depend on past and present mortality, fertility rates and, to a much lesser degree, on net migration.
