In presenting this analysis of the economic aspects of the Blackfeet Indian Reservation in relation to the livestock industry, we have in several instances taken data compiled for Glacier County and applied it directly to the reservation. The area of the Blackfeet Reservation and Glacier County is coincident except that Glacier County includes eight townships, comprising a narrow strip on the east, that are not a part of the reservation, and the reservation includes seven townships that form a part of Pondera County on the south.

In all statistics and other information pertinent to the range livestock industry, the county data will apply directly and quite accurately to the reservation. Stock raising is by far the most important, and the one outstanding industry of the region. The counties to the south and east produce a greater value of farm crops than of livestock, but Glacier County, probably on account of the available range lands on the reservation, is distinctly a range livestock county and as such may be considered as a “distinct economic territory.” The figures show the livestock industry of Glacier County to annually produce approximately three and one half times the income of its nearest competitors.”

[In 2007 the Census of Agriculture, County Profile, Glacier County, Montana showed the Market Value of Livestock and Crops Products Sold to be around $61,000,000 with another $6,000,000 in Government Subsidy Payments for a total value of $67,000,000 per year from former Indian allotments on the reservation.]
