Map of Canada highlighting the three prairie provinces, Alberta, Saskatchewan and Manitoba.
For perspective, the country of France is about one-third the size of the three prairie provinces combined (0.643M km2) and in 2006 had a population that was 12x as large (63.62M)–see http://data.worldbank.org/indicator/SP.POP.TOTL?location=FR. Abbreviations: NL Newfoundland; NB New Brunswick; PEI Prince Edward Island.

Tuberculosis cases in the prairie provinces of Canada between July 1, 2006 and December 31, 2010.
Population group information was missing for two of the 1069 “other” culture-positive cases; of the 26 cases meeting the original study inclusion criteria and designated a secondary case, 25 were Indigenous and 1 was non-Indigenous.
