2024 Kansas Population Forecast Race and Ethnicity Report
This report series presents findings on population growth in Kansas over a fifty-year period from 2022 to 2072. The research conducted by the Center for Economic Development and Business Research, with funding from the Patterson Family Foundation, forecasted population growth for different regions in Kansas by race, Hispanic origin, age, and sex. The projections utilize comprehensive data on statewide and regional population, birth, mortality, and migration rates for various demographic groups.
According to the forecasts, Kansas’s total population is projected to grow by over 469,000 residents by 2072, signifying a cumulative increase of 16% compared to the 2022 population. The expected growth rate is 0.3% annually until 2072, representing a modest decline from the higher growth rate experienced between 1960 and 2010 (0.54%), though markedly higher than the 0.3% annualized growth seen between 2010 and 2022.
Annualized growth rates vary, with a relative slowing between 2032 and 2052 as Baby Boomers and Gen-Xers reach ages of higher mortality. Despite this apparent slowing, fundamental drivers are on the increase throughout this period, such as growing birth counts and increasing diversity. From 2052 onwards, the forecasts estimate a wave of population growth that exceeds Kansas’ growth between 2010 and 2020 (0.3%). Notably, the growth trends differ among different groups within the state, influenced by factors such as age, urban or rural location, and race or ethnicity.
This report will further detail population growth by race and Hispanic ethnicity. A significant factor in the forecasted population growth across the state is the growing diversity of race and Hispanic ethnicity. Higher fertility rates among the population that identifies as non-White or of Hispanic origin are set to shift the racial and ethnic demographics of the state dramatically.
The fraction of the White population statewide is expected to fall from 85.1% in 2022 to 79.5% in 2072, a shift of 5.7 percentage points. This contrasts with the 6.7% growth in count of the white population, which is substantially overshadowed by the percentage growth of other races and the Hispanic population. For the Hispanic population and Black and Other Races, population growth begins notably higher than for the White population before tapering off somewhat through the later forecast years. This tapering does not represent a reduction in fertility rates, but rather that as these populations grow, the number of births in each 5-year period represents a progressively smaller fraction of the total population of each demographic over time, even considering that more individuals of each demographic are entering their years of peak fertility. Further, these growing populations are aging, and thus, the mortality figures show notable increases among these minority populations. This can be seen clearly in the previous table, as though the number of births for each minority group is increasing throughout the forecast, deaths see even greater increases relative to the levels seen in 2022.
Some regions are forecast to shift by even wider margins. In South Central Kansas, the large Black and Other Race populations in Wichita grow significantly in share, with White race declining by 6.5 percentage points of the total. In the Northeast region, the share of the White race alone falls by 7.4 percentage points, the largest racial change for a whole region in the state. Even wider, however, are the 50-year shifts in the share of the population identifying as of Hispanic ethnicity, regardless of race. Statewide, the Hispanic population is expected to grow from 13.8% in 2022 to 19.5% in 2072, a swing of 5.7 percentage points. In South Central Kansas, the swing is forecast to be 7.3 percentage points, with a resultant 21.3% of the population identifying as of Hispanic origin in 2072. The most significant Hispanic population growth, as a fraction of the total, is in the Southwest region. As of 2022, 42.5% of the Southwest’s population identifies as Hispanic, and by 2072, the forecast expects this share to climb to 60.3%, a massive 17.9 percentage point growth.
Kansas will undergo significant changes in its population distribution and demographic composition over the next five decades. Understanding these trends will be crucial for policymakers and businesses to plan and address these shifts' unique challenges and opportunities.

Methodology Updates and Notes
This data represents an update to, and evolution of, CEDBR’s 2023 50-year population forecast from 2021-2071, funded by the Patterson Family Foundation. Broadly, the methodology remains consistent with the 2023 forecast, with two primary updates. First, the starting year has been updated to 2022 from 2021 and now utilizes the Census 5-Year American Community Survey Estimates instead of the 2021 estimates used last year, with subsequent forecasted years adjusted later by one year to remain consistent with the 5-year interval. These five-year intervals are necessary to align with Census ACS age by sex and race/ethnicity data for each county.
The second update within the methodology is a more accurate simulation of the elderly population’s carryover related to mortality between periods. In the 2021-2071 forecast, the population aged 85 and older was subjected to the average mortality rate for all persons over the age of 85, which would then appear in the next period’s estimates. That sum total population 85 and older in the second period was again subjected to the same mortality rate to calculate the carryover to the third period, and so on. In the new 2022-2072 forecast, this carryover population has been calculated by instead identifying the 5-year age cohorts beyond age 84 and subjecting each, individually, to the respective mortality rates for those age groups rather than the average and applying the survivors back into the population in subsequent periods, reported simply as 85 and older to maintain consistency.
The reason this is important for accurately predicting elderly populations is due to how this more closely reflects actual mortality. Individuals aged 95 to 100 naturally have higher mortality rates than individuals aged 85 to 90, and thus the former were previously being overrepresented in the 2021-2071 estimates during the years in which a significant remnant cohort was carried forward five or ten years beyond what would realistically be expected. In effect, this change somewhat reduced the mortality rate for individuals aged 85 to 89 while increasing it notably for individuals aged 90 and above. The chart below compares the inverse mortality rates; the survivorship rates for each 5-year age cohort, which represents the percent chance an individual has of surviving the previous 5 years to reach each listed age cohort’s starting year. Note that an individual’s chance of surviving to age 85 is higher in the 2024 estimates than in the 2023 estimates but continues to decline over time, while in the 2023 estimates the survivorship rate remains the same as they age into older age cohorts.
A vision of how this change impacts the model is by comparing models in their estimates of the same year using linear interpolation between each period. By lining the models up in this way, it is evident that the revised methodology avoids some of the volatility in this population seen in the 2023 estimates, though broadly reflects the same trends, particularly mitigating the notable decline seen through 2026 in the prior model. The net effect of this change is a more stable population in this age group, less influenced by survivorship of the generational echo cohorts that were surviving beyond what is reasonable given the fact that mortality rates increase very sharply beyond age 85.
