Idaho vs. United States
Comparative Trends Analysis:
Population Growth and Change, 1958-2021
Introduction
Idaho vs. United States
Idaho:
2021 Population = 1,900,923
2021 Percent of U.S. = 0.6%
U.S.:
2021 Population = 331,893,745
Attracting and retaining people to live, work, raise a family, and retire underlies the economic vitality of any region. Population growth is both a cause--and a consequence--of economic growth. Patterns of population growth and change reflect differences among regions to attract and retain people both as producers and consumers in their economy.
The following graphs offer a broad overview of trends in the pattern of population growth and change of Idaho with comparisons to the nation at large. The data used are those compiled by the Regional Income and Product Divisions of the Bureau of Economic Analysis, U.S. Department of Commerce.
Population, 1958-2021
Population, 1958-2021
Figure 1.
Figure 1 traces Idaho's annual population for the period 1958-2021 to illustrate population patterns over time. During this 64-year period, Idaho's population rose from 646,000 in 1958 to 1,900,923 in 2021, for a net gain of 1,254,923, or 194.3%.
NOTE: The state population totals reported by the Bureau of Economic Analysis (BEA) are from the Bureau of Census midyear (July 1) estimates. These estimates may differ from those prepared independently in some states by various agencies and/or universities.

Figure 2.
Figure 2 shows Idaho's population growth in a broader context by offering direct comparisons across time with the United States. The growth indices shown here express each region's population in 1958 as a base figure of 100, and the populations in later years as a percentage of the 1958 base figure. This method allows for more direct comparison of differences in population growth between regions that may differ vastly in size.
Idaho's overall population growth was 194.3% over 1958-2021 outpaced the United States' increase of 90.6%.

Figure 3.
Another interesting and insightful way of highlighting the population growth of Idaho is to trace its individual percentage contributions to the United States' total population over time, as shown in Figure 3. A rising share means a region's population grew faster, or declined less, than the United States' population, while a declining share shows it grew more slowly.
In 1958, Idaho's population totaled 0.37% of the United States' population, while in 2021 it totaled 0.57% thereby yielding a +0.20% share-shift.

Figure 4.
Figure 4 highlights the short-run pattern of Idaho's population growth by tracking the year-to-year percent change over 1959-2021. The average annual percent change for the entire 63-year period is also traced on this chart to provide a benchmark for gauging periods of relative high--and relative low--growth against the backdrop of the long-term average.
On average, Idaho's population grew at an annual rate of 1.73% over 1959-2021. The state recorded its highest growth in 1993 (3.46%) and posted its lowest growth in 1963 (-1.30%). In 2021, Idaho's population grew by 2.88%

Figure 5.
Over the past six decades some states have experienced extreme swings in growth, and often such swings have tended to coincide with the decades themselves. Figure 5 again shows the annual percent change in Idaho's population since 1959, but this time they are displayed with average growth rates for the decade of the 1960s, 1970s, 1980s, 1990s, 2000s, 2010s, and 2020-2021.
During the 1960s, Idaho's annual population growth rate averaged 0.74%. It averaged 2.81% in the 1970s, 0.65% in the 1980s, 2.52% in the 1990s, 2.00% throughout the 2000s, 1.52% during the 2010s, 2.54% thus far this decade (2020-2021).

Figure 6.
Figure 6 compares the decade average growth rates for Idaho noted in the previous graph with the corresponding decade averages for the nation.
Relative to nationwide population growth trends, Idaho lagged the nation in the 1960s (0.74% vs. 1.29%), recorded above the nation over the 1970s (2.81% vs. 1.10%), recorded underneath the nation during the 1980s (0.65% vs. 0.95%), outpaced the nation during the 1990s (2.52% vs. 1.23%), recorded above the nation in the 2000s (2.00% vs. 0.95%), outpaced the nation during the 2010s (1.52% vs. 0.74%), and topped the nation over 2020-2021 (2.54% vs. 0.25%).
