1. You are interested in the rate of food insecurity in your region and if it is higher than food insecurity in Canada as a whole. You have access to national food insecurity data (see table below). Although you suspect that food insecurity may differ by sex, there are unfortunately no sex-specific data available for food insecurity in your region. The only information you have about your region is that the population is 20,000 (11,500 men and 8,500 women) and that there were a total of 2,250 cases of food insecurity reported. You wonder how much food insecurity would be expected in your region if it had the same level of food insecurity among men and women in the Canadian population.

Household food insecurity by sex in Canada, 2020

Sex	Canadian population (standard)	Number reporting moderate to severe food insecurity in Canada
Males	18,885,776	1,989,000
Females	19,121,390	2,154,000

Show all steps of your calculation in Parts A to D, including formulae, and be sure to provide a summary sentence for each question, stating your results in full.

1. What is the crude rate for food insecurity in Canada in 2020?
2. What are the rates of food insecurity in men and women in Canada in 2020?
3. What is the crude rate for food insecurity in your region in 2020?
4. Calculate the appropriate measure, standardized for sex, to determine how food insecurity in your region compares to Canada overall.
5. Discuss whether the results you have calculated in Parts A to D support your earlier hypotheses of:

i) differences in food insecurity rates by sex; and

ii) differences in food insecurity rates in your region compared to Canada overall.

Be sure to support your points by citing data.
