I read a paper studying the
correlation between rates of cigarette smoking and lung cancer
incidence in the United States. It seems pretty common knowledge today that cigarettes contribute to cancer, but this paper offered some insights into the issue I had previously not thought of. The paper, found here,
analyzes these two things based on different birth cohorts and
provides figures showing lung cancer incidence from the early 20th
century, lung cancer based on different cohorts and smoking rates in
teenagers. However, the figures offer an overly specific analysis
with too narrow of a date ranges to show the change in lung cancer
incidence in relation to change in smoking rates nationally. In
order to get a better visual of how the rates mimic each other I
decided to create a figure presenting smoking rates and lung cancer
incidence for both males and females in the United States from
1965-2005. The data for smoking came from the CDC and the data for
lung cancer came from the American Lung Association.
Here are the figures I used before I
combined the lines.
First the lung cancer figure from the American Lung Association:
Here is my figure I created by
combining the data from the two figures:
The X axis is the date and
the Y axis has no numerical significance; the figure is just used to
show the relationship between the two figures better. The blue line
represents the smoking rate in males, and the red line is for
females. The green line represents male lung cancer incidence and
the yellow is for females.
