To find the number of children in Illinois between the ages of 10 and 14, we
first found the percentage of kids in each state between the ages of 10 and
14. Then we eliminated states that we thought would have families different
from Illinois due to the reasons people live there. For example, California
would mostly be populated by celebrities and people fresh out of college. We
also eliminated the District of Columbia, because most of the people who live
there work for the government and either have grown children or are too busy
for kids. Then we averaged the remaining percentages of kids 10 to 14 in the
states we felt had similar types of families (Alabama, Wisconsin, and Oklahoma).
We then took the average percentage and multiplied it by the population of Illinois
and came to our conclusion that there were 843,600 children ages 10 to 14 living
in Illinois in 1990.
Thanks for the challenge!,
