Per Capita Income (PCI) is one of the most widely used indicators for gauging the economic performance and changing fortunes of local economies. It is used as a yardstick to assess the economic well being of a region's residents and the quality of consumer markets. It serves as a barometer for calibrating the economic performance of a region over time and to judge differences in relative economic prosperity between regions. Shifting trends in local per capita income growth have important social and political ramifications and significant implications in formulating local economic development strategies and initiatives.
Data Definition:
This measure of income is calculated as the total personal income of the residents of an area divided by the population of the area. Per capita personal income is often used as an indicator of consumers' purchasing power and of the economic well-being of the residents of an area.
Personal income is measured as a flow throughout the year, while the measurement of population is at one point in mid-year. Therefore, per capita income is distorted if a significant change in population occurs during the year.
For smaller counties in particular, per capita income in any given year may be exceptionally high or low for the short run because of unusual local conditions, such as a bumper crop, a catastrophe, or a major construction project as the building of a dam or nuclear power plant.
Farm incomes are notorious for being especially volatile year-to-year, owing to changing weather, commodity market conditions, and alterations in government programs. Therefore, the per capita income of farm-dependent counties may exhibit sharp fluctuations over time.
The presence of large institutional populations--such as residents attending a local college or the residents of a local prison or state mental institution--can significantly lower the per capita income estimates of an area. Such results may not reflect the relative economic well being of the non-institutional population and may mislead if care is not given to their interpretation.

Figure 3.
Figure 3 shows Colusa County's real per capita personal income growth in a broader context by offering direct comparisons across time with California, the United States. The growth indices shown here express each region's real per capita personal income in 1969 as a base figure of 100, and the real per capita personal incomes in later years as a percentage of the 1969 base figure. This method allows for more direct comparison of differences in real per capita personal income growth between regions that may differ vastly in size.
Colusa County's overall real per capita personal income growth was 55.8% over 1969-2018 trailed California's increase of 151.6%, and fell below the United States' increase of 156.4%.

Figure 5.
Figure 5 displays the short-run pattern of Colusa County's real per capita personal income growth by tracking the year-to-year percent change over 1970-2018.

Figure 6.
Over the past five decades some counties have experienced extreme swings in growth, and often such swings have tended to coincide with the decades themselves. Figure 6 again shows the annual percent change in Colusa County's real per capita personal income since 1970, but this time they are displayed with average growth rates for the decade of the 1970s, 1980s, 1990s, 2000s, and 2010-2018.
During the 1970s, Colusa County's annual real per capita personal income growth rate averaged 3.01%. It averaged 0.21% throughout the 1980s, 1.27% in the 1990s, 2.75% throughout the 2000s, and 0.74% thus far this decade (2010 to 2018).

Figure 7.
Figure 7 compares the decade average growth rates for Colusa County noted in the previous graph with the corresponding decade averages for California and the nation. As the chart reveals, Colusa County's average annual real per capita personal income growth registered above California's average during the 1970s (3.01% vs. 2.16%), posted below California's average in the 1980s (0.21% vs. 1.62%), amounted to less than California's average during the 1990s (1.27% vs. 1.73%), exceeded California's average during the 2000s (2.75% vs. 1.12%), and lagged California's average over the 9 year period of the last decade, 2010-2018 (0.74% vs. 3.11%).
Finally, relative to nationwide real per capita personal income growth trends, Colusa County outpaced the nation during the 1970s (3.01% vs. 2.37%), recorded underneath the nation in the 1980s (0.21% vs. 2.20%), lagged the nation throughout the 1990s (1.27% vs. 2.03%), exceeded the nation over the 2000s (2.75% vs. 1.09%), and lagged the nation over 2010-2018 (0.74% vs. 2.11%).
