Food security-consistent access to enough food for an active,
healthy life-is essential for health and good nutrition. The extent
to which a nation's population achieves food security is an
indication of its material and social well-being. Differences in
the prevalence of household-level food insecurity between Canada
and the United States are described at the national level and for
selected economic and demographic subpopulations. Associations of
food security with economic and demographic characteristics are
examined in multivariate analyses that hold other characteristics
constant. Comparable measures of household food security were
calculated from the nationally representative Canadian Community
Health Survey Cycle 2.2 (2004) and the U.S. Current Population
Survey Food Security Supplement (2003-05). Based on the standard
U.S. methodology, the percentage of the population living in
households classified as food insecure was lower in Canada (7.0
percent) than in the United States (12.6 percent). The difference
was greater for the percentage of children living in food-insecure
households (8.3 percent vs. 17.9 percent) than for adults (6.6
percent vs. 10.8 percent). These differences primarily reflected
different prevalence rates of food insecurity for Canadian and U.S.
households with similar demographic and economic characteristics.
Differences in population composition on measured economic and
demographic characteristics account for only about 15 to 30 percent
of the overall Canada-U.S. difference.
