Hi guys,
I've seen those words in some writings but can't figure out the meaning.
What does that mean? Is it a common usage?
For your reference, some of the writings are as follows below.
Thanks

Thus we see that, for a time, increasing age means increasing income, and therefore a probable boost 75 in income-tenth position. Although there are no extensive data in the matter, it can be confidently asserted that the higher income-tenths have a much greater representation of spending units headed by persons aged thirty-five to fifty-five than do the 80 lower-income-tenths. This is demonstrably the case among the richest 5 percent of the consumer units. The real question is: To what extent does distribution of income-tenths within a certain age group deviate from dis tribution of income-tenths 85 generally?
