Quebec's population data has a very high level of accuracy, completeness and temporal depth. The infrastructure intégrée des microdonnées historiques de la population du Québec (IMPQ) contains more than 12 million individual mentions and 300 family links created from the matching of old census and civil status data.

In the early 20th century, fertility levels varied among Quebec cities. In Quebec City, the family size of leather workers (shoemakers and tanners) was larger than the observed average. Part of the explanation for this phenomenon lies in the gender and generation relationships that characterize this socio-professional group.

Between 1840 and 1930, 900,000 people left the province of Quebec for the United States. The majority of French Canadians living in the United States at the beginning of the 20th century was concentrated in the six New England states, but over 300,000 lived elsewhere in the country, as far away as California.
