Expenditure Pattern of Wage-Earner Families in Chicago, Illinois, in 1935-36.

1. It should be noted that these lines are cumulative. The line numbered 5 represents

on the expenditure scale the amount spent for 5, 4, 3, 2, and 1. The difference between 4 and 5 is the amount spent for "fuel, light, and refrigeration."

2. If line 17 is above 16, the families in that income band were not in debt at the end

of the year; if line 17 is below 16. the family income did not cover expenditures.
