The medical staff has asked for a report that details the incidence and prevalence rates for diabetes, cancer, and arthritis for the past 3 years. It is your responsibility to collect the information and calculate the rates for each. The mid-interval population for 2013 was 55,000, for 2014 it was 56,000, and for 2015 it was 55,000.

Health Condition	2013		2014		2015

Arthritis	624	9,456	565	10,548	776	9,747

1. What number would be contained in the numerator for the incidence rate for cancer in 2013? _________

2. What number would be contained in the denominator for the incidence rate for cancer in 2013? __________

3. The diabetes prevalence rate means that for every thousand people in 2014, there are ________________ people with diabetes.
