The more up-to-date statistics used by most governments and all international organizations are often interpolated and/or extrapolated from past surveys. The table shows the number of years that have elapsed, on average, between the last national on-the-ground surveys and the year 1995.
In some cases, governments may have more recent statistics that have not yet been made available to the United Nations.
The average age of data has recently been sharply reduced in the 47 countries with published DHS surveys.
A small number of countries have no known data at all under certain headings. Published data for such countries usually represent estimates based on neighbouring countries at similar levels of GNP per capita.
