They give the total population too -- 5,182,617 in 2024-- which is down 3.6% from 2000.

If the number of households is also down by 3.6%, that would come to 1,902,900 households.

3,200 households is 0.17% of the total number of households (one in 595 households)

Averaging this largess over all households (or figuring out what it costs in taxes on average)

$7.5 million/year / 1.903 million households is $3.94 per household/year
