3.4 MAPPING OF DATA SOURCES
A mapping of data sources consists of an inventory of sources available at the level of the country, state, province, or other geographic/administrative unit (12). It involves identifying and describing all the data sources available in the country in order to determine the possible sources that can be used to develop the health indicators. Mapping can help identify gaps and the need for new and/or complementary data sources to develop appropriate health indicators. If there is a paucity of data in a particular area or program component, it is important to collect the data for subsequent analysis. The mapping of data sources involves:
- Constructing a list (by type) of all available data sources used in formulating health-related indicators in the country together with the time period covered by the data set. Where relevant, preparing the same list with additional sources at the state, province, and community levels.
- Constructing a table with information on each source's level of disaggregation, insofar as this is pertinent for the analysis of health indicators.
