Dowling Distribution in Canada in 1901

Numbers are taken from the 1901 census (to match as close as possible the available Irish census of 1901). I have shown figures of one Dowling-per-thousand of population as this better shows distrubution. Raw numbers contain no context of the remaining population and, consequently, show a bias to where Dowlings are rather then where they figure most strongly. This translates into more Dowling's numerically in big city provinces but gives no clue as to origin. In this Canada context I see point of origin as point of arrival and major settlement. The Dowling per thousand approach shows the bias towards the arrival points, in particular, Nova Scotia, Prince Edward Island and Ontario which would take those coming into Canada from the United States. The big surprise, for me, is the large number of Dowling's in Northwest Territories... remember this is one-per-thousand of a very small population over a massive geographical area. What made us head there? (Note: this does not include variations on the name)

Distribution of Dowlings per Thousand of Population Across Canada in 1901 from Census
The chart uses data transferred from the Find My Past 1901 census search and entered by hand into a Microsoft Excel spreadsheet. After some simple formulas this was then charted automatically in a map. The charting application is good at working out the modern provinces but not the 1901 version where the Northwest Territory included Provinces now separate in their own right.
