Boulder County vs. Colorado
Comparative Trends Analysis:
Population Growth and Change, 1969-2017
Introduction
Boulder County:
2017 Population = 322,514
2017 Percent of State = 5.8%
Colorado:
2017 Population = 5,607,154
2017 Percent of State = 1.7%
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 Boulder County with comparisons to Colorado and the nation at large. This analysis features alternative approaches toward discussing, diagnosing and comparing Boulder County vs. Colorado's population growth over 1969-2017. The data used are those compiled by the Regional Income and Product Divisions of the Bureau of Economic Analysis, U.S. Department of Commerce.

Figure 1.
Figure 1 tracks Boulder County's annual population for the period 1969-2017 to illustrate population patterns over time. During this 49-year period, Boulder County's population rose from 129,577 in 1969 to 322,514 in 2017, for a net gain of 192,937, or 148.9%.
NOTE: The county and 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 tracks Colorado's annual population for the period 1969-2017 to illustrate population patterns over time. During this 49-year period, Colorado's population rose from 2,166,000 in 1969 to 5,607,154 in 2017, for a net gain of 3,441,154, or 158.9%.

Figure 3.
Figure 3 portrays Boulder County's population growth in a broader context by offering direct comparisons across time with Colorado, the United States. The growth indices shown here express each region's population in 1969 as a base figure of 100, and the populations in later years as a percentage of the 1969 base figure. This method allows for more direct comparison of differences in population growth between regions that may differ vastly in size.
Boulder County's overall population growth was 148.9% over 1969-2017 trailed Colorado's increase of 158.9%, and topped the United States' increase of 61.8%.

Figure 4.
Another interesting and insightful way of highlighting the population growth of Boulder County is to trace its individual percentage contributions to Colorado's statewide population over time, as shown in Figure 4. A rising share means a region's population grew faster, or declined less, than Colorado's population, while a declining share shows it grew more slowly.
In 1969, Boulder County's population totaled 6.0% of Colorado's population, while in 2017 it totaled 5.8% thereby yielding a -0.2% share-shift.

Figure 5.
Figure 5 shows the short-run pattern of Boulder County's population growth by tracking the year-to-year percent change over 1970-2017. The average annual percent change for the entire 48-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, Boulder County's population grew at an annual rate of 1.94% over 1970-2017. The county posted its highest growth in 1972 (7.46%) and recorded its lowest growth in 2002 (-6.89%). In 2017, Boulder County's population grew by 0.42%

Figure 6.
Over the past four decades some counties have experienced extreme swings in growth, and often such swings have tended to coincide with the decades themselves. Figure 6 again depicts the annual percent change in Boulder County's population since 1970, but this time they are displayed with average growth rates for the decade of the 1970s, 1980s, 1990s, 2000s, and 2010-2017.
During the 1970s, Boulder County's annual population growth rate averaged 3.77%. It averaged 1.80% throughout the 1980s, 2.49% in the 1990s, 0.29% during the 2000s, and 1.20% thus far this decade (2010 to 2017).

Figure 7.
Figure 7 compares the decade average growth rates for Boulder County noted in the previous graph with the corresponding decade averages for Colorado and the nation. As the chart reveals, Boulder County's average annual population growth exceeded Colorado's average throughout the 1970s (3.77% vs. 2.78%), exceeded Colorado's average in the 1980s (1.80% vs. 1.41%), recorded under Colorado's average throughout the 1990s (2.49% vs. 2.58%), fell below Colorado's average during the 2000s (0.29% vs. 1.64%), and recorded under Colorado's average over the 8 year period of the last decade, 2010-2017 (1.20% vs. 1.51%).
Finally, relative to nationwide population growth trends, Boulder County led the nation in the 1970s (3.77% vs. 1.10%), registered above the nation over the 1980s (1.80% vs. 0.95%), exceeded the nation in the 1990s (2.49% vs. 1.23%), fell below the nation during the 2000s (0.29% vs. 0.95%), and exceeded the nation over 2010-2017 (1.20% vs. 0.75%).
