thousand

dollars

to less than 100

thousand

dollars

in that 7 years had a plateau proportion with only one-fifth for 50 to 75

thousand

dollars

and less than 15% for the others.

amount

of wages which were between 25,000 to 50,000

dollars

after a 4% growth between 2007 and 2011 which was the peak in 2011, levelled off in 2015 to where it started.
