2005 GCS_North_American_1984 Census Data

I would like to establish how I created the age layer. I took the age     groups  18-21 and age 22-29 and combined them into a column called both.  This is different from the book but helps me keep it straight in my mind. The total of both was 221,435. The total population was 1,077,534. So I created a new column called percent. Percent was filled by field calculator with the following calculation: both divided by 221,435 (total of both). I believe this to be the percent of 18-29 year olds in that particular census tract.

Q2)    Discuss the two weighted overlays.
