Births and deaths are INSEE's civil registration, by place of residence. INSEE publishes no yearly migration for places, so migration here is what is left of the population change once births and deaths are taken out, and each year's population is itself drawn from five years of census surveys: read it as a trend. France counts no homes finished, so homes started (SDES Sitadel) stand in; most are finished about two years later. A home houses a household, not a person: two or three new residents per new home is roughly one home per new household.
