To determine the inflated Poverty Line Prices, we took the average price of Bay Area necessities and calculated the percentage of take-home pay each item would represent for a family living on the poverty line earning $24,300. After taxes, that's $22,222.

For example, eggs represent 1.4% of the average weekly income for a family living on a poverty line income. The percentage of salary required to purchase each item was then applied to the average San Francisco take-home salary.

If eggs cost $6 for someone living on the poverty line, or 1.4% of their weekly salary, the adjusted price would be $29.64 for someone living on the average San Francisco salary.

The San Francisco average salary was provided by the US Census Bureau. The average item costs were provided by expatistan.com, and the national price for textbooks was provided by collegeboard.org.
