To make cross-time comparisons using the March CPS data more feasible, variables in IPUMS-CPS are coded identically or harmonized across time. This harmonized dataset is also compatible with the data from the U.S. decennial censuses that are part of the Integrated Public Use Microdata Series (IPUMS-USA).
Martinique has a population of 386,486 (January 2013). There are an estimated 260,000 people of Martiniquan origin living in mainland France, most of them in the Paris region. Emigration was highest in the 1970s, causing population growth to almost stop, but it is comparatively light today.
