Together the United States and Canada comprise 12.5% of the world’s land area and produce over 25% of its economic output. The authors aim to understand these two important countries from the perspective of geography, examining the spatial distributions of their environments and people. Rather than breaking the countries down into regions, Leonard et al. approach the geography systematically. Important topics in both physical and human geography are covered, including landforms, biogeography, climate, population, economy, culture, and urbanization. Heavily illustrated with maps, photos, and figures throughout, the sixth edition of The United States and Canada continues to guide geography students to a deeper understanding of the countries they call home.

Beginning in 1956 each vol. includes as a regular number the Blue book of southern progress and the Southern industrial directory, formerly issued separately.
