Explore how IPUMS created this variable
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:
- Harmonization table
- No supplemental programming
- Instructions for interpreting harmonization documents
Description

Click on the Source Variables tab for information on place of residence for each sample year. Source variables may contain more geographic unit detail but are not suitable for cross-temporal comparison.
Comparability — General
Where boundaries changed over time, units were harmonized to create units with boundaries that remain stable over time.
Boundary changes:
- 1980: Point Fortin region split from Saint Patrick county.
- Between 1990 and 2000:
- St. Patrick became Siparia.
- St. Andrew/St. David and a small part of county of Nariva/Mayaro became Sangre Grande.
- Victoria became Princess Town.

- Tabaquite and Talparo formed from Couva
- Piarco formed from Tunapuna
County codes above 99 and below 900 indicate counties in the 1990 sample that could not be combined with the 2000 sample due to changes in geography.

The main objective of this section is to determine the relative directions in which the local born population have tended to move over periods of one, five, and ten years. Migration is even more important when cross classified with age, sex, ethnic groups, levels or educational attainment and level of training.
Internal migration also provides vital information on the direction of the flow of the population from rural to urban areas. It also allows the determination of migration streams and volume of movement over time. Migration is also a major factor in population change and in the redistribution of population among geographic areas.
Questions 9 - Address one year ago and question 10 address 5 years ago
Where these questions do not apply i.e. in cases when the individuals are less than one (1) year old and less than five (5) years old respectively, put not applicable (N.A.) in the space for the address. Do not make any entries. If it is a foreign address, just note the name of the country.
