Ancestor Mobility in 1911

This bar chart from 1911 census data shows in blue the fraction of people born in a province still living in it, and in red the fraction of those living there who were born there.

Those born in BC were most likely to stay, Manitoba-born least likely.

From Manitoba westward more than half the residents were born outside the province, a reflection of those flocking to "The Last Best West". PEI had a net outflow — more born there than living in the province.

The figures are sourced from Ancestry.ca census data.
