Question

Part C

Consider 2 populations:

Population A includes 50,000 cancer- free people at the beginning of 2014. During 2014, there were 4,000 cancer deaths.

Population B include 52,000 cancer-free people at the beginning of 2014. During 2014, there were 5,080 cancer deaths.

1. What are the incidence (cancer mortality) rates in Pop A and Pop B? Remember to include the time period and use 10,000 as your multiplier. Show your work (1 pt)

Incidence rate =

Number of new cases over a time period                         X 10,000

Average population at risk during the same time period

Population A:   4,000 cancer deaths              

                         50,000 cancer-free people in 2014                  x 10,000 =

0.08 x 10,000 = 800 cancer mortalities per 10,000 (incidence rate)

Population B:     5,080 cancer deaths

                            52,000 cancer-free people in 2014           x 10,000 =

0.097692 x 10,000 = 976.92 or 977 cancer mortalities per 10,000 (incidence rate)

2. Compare, in words, the crude rates of cancer in Pop A compared to Pop B? (1pt)
