About 1.6 million Canadian households faced some level of food insecurity in 2011, according to a new report.

That amounts to nearly one in eight families who have inadequate access to regular, healthy meals because of financial constraints.

Households with children under the age of 18 are more likely to be food insecure, says the study, which does not include data from homeless people.

More than 1.1 million children, or one in six, were living in a home where people reported struggling to put food on the table in 2011.

Nunavut, Prince Edward Island and New Brunswick had the highest prevalence of children living in food-insecure households at 57 per cent, 27 per cent and 25 per cent respectively.
