Subnational Sample Design

In MICS, most samples are representative at the national level. However, there are two main types of subnational samples:

See the country specific reports for further details about the sample design.

Subnational samples are identified in IPUMS in the following ways:

  • In the data selection tab, they appear with a purple circle i icon and explanation of the sample.
  • In the SAMPLE variable.
  • In the SUBNATIONAL variable.
  • Using a letter to identify the sample in the sample ID. The letter "a" following a sample name indicates a national sample. Any letter other than "a" (for example "b", "c", "d", etc.) represents a subnational survey. These letters are only used to differentiate the samples and are assigned based on the order in which samples are released.
  • Some samples have both a national sample and sub-national sample within the same year. If only a sub-national sample is listed, there is not a national sample.

    The following samples have an identified population or a subnational geographic unit included in the sample design:
