How to read the data

The data printouts are structured in tabular form with a top row bearing the name of the country and 11 columns containing the following information:

Column 1 Administrative level. Country data are specified as national, regional, province, district or local, depending on where the survey took place and for which administrative level it is representative:

National: A nationally representative sample. Regional: The survey covers several sub-national levels. Province: The survey was performed in a province or state (name presented in the Notes column). District: The survey is representative of a district (name presented in the Notes column). Local: A community, a village or a town was surveyed (name presented in the Notes column).

Column 2 Dates of survey. This column gives the month and year during which the survey took place

Column 3 Area. URBAN and RURAL specify the setting. If no specification is given, data refer to both urban and rural areas.

Column 4 Sex. Male is signified as M and female as F. If no specification is given, data refer to both sexes.

Column 5 Age group (years). Every data entry refers to a specific age group, specified in years using the decimal system, i.e. the month ranges have been transformed into the decimal system and are presented in years with two decimals. The following age groups appear in the printouts:

0. -4.99 years meaning 0-59 completed months; 0.00-0.49 years meaning 0-5 completed months; 0.50-0.99 years meaning 6-11 completed months; 0.00-0.99 years meaning 0-11 completed months; 1 year meaning 12-23 completed months; 2 years meaning 24-35 completed months; 3 years meaning 36-47 completed months; 4 years meaning 48-59 completed months; 5 years meaning 60-71 completed months.
