Whether measured by changes in the range of per capita incomes or by changes in the coefficient of variation (CV), there was substantial convergence in total per capita personal income from 1950 to 1999.
The convergence in State per capita income in 1950-99 occurred almost entirely during the first 29 years.
Because earnings accounts for such a large share of personal income, the convergence of per capita income in 1950-79 and the absence of convergence since 1979 are largely attributable to per capita earnings.
From 1973 to 1987, the pattern of the CV was noticeably affected by a surge in per capita income in Alaska that was almost entirely due to the construction of the Alaska pipeline.
There were substantial geographic shifts in per capita income among States (see map 1 on page 45).
A third possibility is that further convergence did not occur because the States had reached their long-run rates of per capita income growth in 1979.
c) Jurisdictions whose residents' per capita income is more than 120 percent of the state average but equal to or less than 160 percent of this figure would receive "half funding" under the Act.
d) Jurisdictions whose residents' per capita income is 120 percent or less of the state average will receive "full funding".
As with per capita income, median income growth between the 1990 and 2000 censuses was stronger in most Fourth District counties than in the nation as a whole.
In both states, the gap between national and state per capita income increased over the last 30 years, with the gap's growth accelerating in the late 1990s.
In the 1970s, Ohio enjoyed per capita income levels near national averages but it has fallen behind since then.
