The European population grew slowly under French rule, thus remained relatively low as growth was largely achieved through natural births, rather than by immigration. Most of the French were farmers, and the rate of natural increase among the settlers themselves was very high. The women had about 30 per cent more children than comparable women who remained in France. Yves Landry says, "Canadians had an exceptional diet for their time." The 1666 census of New France was the first census conducted in North America. It was organized by Jean Talon, the first Intendant of New France, between 1665 and 1666. According to Talon's census there were 3,215 people in New France, comprising 538 separate families. The census showed a great difference in the number of men at 2,034 versus 1,181 women.
