Codes and Frequencies
Most IPUMS data transformations are performed using variable harmonization tables that specify how each value in the source data is recoded. Some variables also require programming logic in addition to the harmonization table. The harmonization documents for this variable are:
ETHNICPH indicates the ethnicity of an individual: the group to which the person traces their family ties by blood, within the Philippines.
Comparability — General
Ethnicity aims to identify ethno-linguistic groups.
The 1990 Philippines sample includes a question more specifically oriented toward language in childhood: mother tongue (MTONGPH). For many purposes MTONGPH and ETHNICPH are likely comparable.
Ethnicities were harmonized by name across sample years. Sample years vary in the level of detail available and their list of identified groups.
