When a region retains a high percentage of residents who were born and raised there, that population stability creates predictable demand for housing, infrastructure, and community facilities. Kansas provides a strong case study in this relationship. According to Census Bureau data released in September 2023, 53.5 percent of people who moved in 2022 did so within the same county and an additional 24.3 percent remained in their state. More than three-quarters of movers stayed close to home. In Kansas, many counties report that over 70 percent of residents were born in the state. This level of retention has direct implications for how construction professionals, planners, and developers approach building projects. In the Kansas City metro area, the need for efficient structural work becomes critical when redevelopment projects must operate around established neighborhoods. The double bridge demolition completed in under three days demonstrates how high-speed structural takedowns can minimize disruption for nearby residents while making way for new construction.
The Link Between Population Retention and Residential Construction Demand
Population retention directly influences how many new homes need to be built, what types of housing are in demand, and where infrastructure investments make the most sense. When residents stay in their home counties generation after generation, housing markets tend to behave differently than in areas experiencing rapid turnover or population loss. Stable retention creates a baseline demand for single-family homes, multi-family units, and rental properties that developers can count on when planning multi-year projects.
Research from Lending Tree released in late 2023 found that 57 percent of millennials and Gen Zers live in their hometowns. This trend has significant consequences for the construction industry. Younger adults staying in or near their hometowns need starter homes, accessory dwelling units, and rental inventory. They also drive demand for renovation work on the homes they grew up in. Areas with high retention rates often see a steady flow of remodeling projects alongside new construction, keeping local contractors busy across multiple market segments. The same demographic patterns that keep people close to family also affect how communities develop. In states where residents stay put, consistent neighborhood populations support long-term planning for schools, roads, and utilities. This predictability benefits construction firms that can invest in equipment, training, and local supply chains with confidence that demand will persist. Counties in Arkansas with the highest life expectancy show similar patterns where stable populations correlate with sustained investment in community infrastructure.
County-Level Retention Data Across Kansas
Stacker compiled data from the Census Bureau ranking Kansas counties by the percentage of residents born in the state using 2022 five-year estimates. The data reveals a wide range of retention rates across the state, from counties where more than 70 percent of residents were Kansas-born to areas with much higher in-migration from other states. These numbers give construction professionals a practical tool for assessing where housing demand is likely to remain steady versus where new residents may shift building priorities.
What the County Data Reveals About Construction Markets
Shawnee County, home to Topeka, reports that 125,413 of its 178,625 residents were born in Kansas, representing 70.2 percent of the population. An additional 24.4 percent came from other states, while 1.1 percent were born in U.S. territories and 4.2 percent were born in another country. This mix of a strong native-born majority with a modest influx of out-of-state residents creates a balanced housing market where builders serve both local families and newcomers.
Urban Versus Rural Retention Differences
Brown County, a smaller rural county with 9,486 residents, shows 6,678 Kansas-born residents at 70.4 percent of the population, nearly identical to Shawnee County’s percentage. Another 28.2 percent came from other states and 0.6 percent from U.S. territories. The similarity in retention rates between an urban county like Shawnee and a rural county like Brown suggests that factors beyond population density drive stay-in-place decisions. For builders, this means construction demand can remain strong across both urban and rural markets within the same state.
| County | Total Population | Born in Kansas | Born in Kansas (%) | Born in Another State (%) |
|---|---|---|---|---|
| Shawnee | 178,625 | 125,413 | 70.2% | 24.4% |
| Brown | 9,486 | 6,678 | 70.4% | 28.2% |
| Riley | 71,959 | 43,895 | 61.0% | 33.5% |
| Sedgwick | 523,824 | 340,485 | 65.0% | 27.8% |
| Johnson | 609,863 | 274,438 | 45.0% | 47.2% |
The table shows how retention varies by county type. Johnson County, part of the Kansas City metro area, has the lowest in-state retention at about 45 percent. Nearly half its residents were born in another state. This pattern reflects how border counties and metropolitan areas attract more out-of-state movers. For construction firms, Johnson County demands a different approach focused on serving newcomers with move-in-ready homes, while counties like Shawnee and Brown require strategies that address multigenerational housing needs and renovation work.
Why Stable Populations Create Predictable Housing Markets
Counties with high percentages of native-born residents tend to have housing markets that behave more predictably than areas experiencing rapid population churn. When families stay in the same county across generations, the housing stock evolves gradually. Homes pass from one generation to the next, creating steady demand for renovations, additions, and updates. New construction fills gaps in the market rather than racing to keep up with sudden population spikes.
Post-pandemic migration data from the Census Bureau shows that many people who moved during COVID-19 chose to relocate within their own state rather than cross state lines. In Texas, moves out of Houston rose 62 percent in the first month of the pandemic, but the western suburb of Katy saw more new residents than any other part of the country. This pattern of moving to nearby suburbs rather than distant states reflects a broader preference for staying close to familiar communities. When residents are rebuilding after disruptions, they tend to reinvest in their existing communities rather than relocate entirely. This creates opportunities for local construction firms that understand the specific housing stock and building codes of their region.
For contractors working in high-retention counties, the steady client base means repeat business and word-of-mouth referrals drive growth. A family that hires a contractor to remodel their kitchen may hire the same firm five years later for a bathroom renovation or a basement finish. This pattern of repeat work is more common in stable population areas than in high-turnover markets where homeowners come and go quickly.
Infrastructure Planning for Communities Where Residents Stay
Population retention affects infrastructure planning as much as it affects housing. When residents stay in place for decades, roads, water systems, schools, and public buildings must serve the same people over long periods. This creates different infrastructure demands than areas experiencing rapid growth or decline. Stable populations need maintenance and upgrades rather than wholesale new construction. Understanding where new Texas residents come from and how migration trends shape housing demand illustrates the contrast with Kansas, where retention rather than in-migration drives the housing conversation.
Matching Infrastructure Investment to Demographic Realities
In Kansas counties with retention rates above 70 percent, infrastructure spending priorities lean toward rehabilitation and expansion of existing systems. Water treatment plant upgrades, road resurfacing, and school additions take precedence over building entirely new utility networks. For construction companies, this translates into a steady stream of public works contracts that require specialized skills in retrofitting, phasing work around active facilities, and coordinating with local government agencies.
Counties with lower retention rates and higher in-migration, such as Johnson County, face different infrastructure pressures. These areas need new schools, expanded road capacity, and additional water and sewer connections to serve growing populations. The construction focus shifts to new development projects, subdivision construction, and large-scale site work. Builders working across multiple Kansas counties need to adapt their services to the specific demographic conditions of each market.
What Construction Professionals Can Learn From Retention Trends
Demographic data on population retention offers practical guidance for construction business strategy. Firms looking for stable, long-term markets should target counties where retention rates exceed 65 percent. These areas offer reliable demand for renovation work, multifamily housing, and infrastructure maintenance contracts. In communities where what makes southeastern towns walkable for residents and visitors includes compact, older neighborhoods, the construction focus shifts toward infill development and streetscape improvements rather than greenfield projects.
Builders entering the Kansas market should also consider licensing requirements and local regulations. The process of how to get a general contractor’s license varies by state, and while the linked guide covers Arkansas, the principle of researching local licensing requirements applies equally to construction work in Kansas. Each county may have its own permitting processes and building codes that affect project timelines and costs.
Historic preservation projects also play a role in high-retention communities. When families stay in the same area for generations, older homes and buildings hold sentimental and historical value that drives renovation and restoration work. The effort involved in saving the Felix Gans House, a Craftsman bungalow on the National Register, shows how preservation projects create specialized construction jobs for carpenters, masons, and restoration specialists. Similar opportunities exist in Kansas communities where century-old homes and downtown buildings need skilled craftspeople to maintain and restore them for continued use.
For construction firms operating in Kansas, the bottom line is clear. Population retention data provides a reliable indicator of where housing demand will remain steady, what types of projects will be needed, and how infrastructure spending will be allocated. Builders who understand these demographic patterns can position their businesses to serve stable, long-term markets with confidence.
