Explanation of the numbers.
The 1830 and 1840 census contained 12 colums of age information for males and 12 columns for females. These were for Free white persons, including heads of families. In addition, there were columns for Employment, Pensioners, Impairment, and Schools. I have only included the information from the age categories, which were:

• To 5
• 5-10
• 10-15
• 15-20
• 20-30
• 30-40
• 40-50
• 50-60
• 60-70
• 70-80
• 80-90
• 90-100
  

This information was repeated for both males and females. An example of how to read the census information presented here would be:

This is translated to read:
Joe Jones found on page 14 of the particular county census with 2 males age 10-15, 1 male 15-20, 1 male 20-30, and 1 male 50-60. Also, 2 females to 5, 1 female 5-10, 1 female 10-15, and 1 female 40-50.
