According to the U.S. Census' most recent American Community Survey:
The median annual pay earned by the 94,000 (or so) Cleveland residents who worked full-time, year-round in 2012 was $32,716.
Divided by 2,080 hours of work, that's $15.73 an hour.
"Median" means that half of the city's 94,000 (or so) fully employed workers earned less. (For comparison, the 2012 median for the whole state of Ohio was $41,759.)
Adjusted for inflation, Cleveland's 2012 full-time year-round earnings median was down 12% from the level found by the Census in 1999 – about $2.16 an hour less.
51% of Cleveland's full-time year-round workers are women. Their median pay earned in 2012 was $30,959. Divided by 2,080 hours of work, that's $14.88 an hour. (Again, this means half of those fulltime female workers made less.)
