$43,430 is the number that the federal government considers to be abject poverty. Clearly it's not though. But use your chart to check the 250% level often used as a cut off for services. You can make a 6 figure income and still be considered poor.
$43,430 split 8 ways is $5428.75/person/year, before taxes.
