Southwest Travis

Portrait

The Southwest Travis Census County Division is the Hill Country corridor along the southwestern edge of Travis County. It is a 172.6-square-mile region wrapping the southern shore of Lake Travis from Westbank and Eanes through Bee Cave and Lakeway to the Pedernales canyons west of Spicewood, with the Oak Hill ridge and the rural reaches of RM 1826 tracing its southeastern boundary. Its population is 86,480, distributed across 35,481 households and 38,059 housing units, for a density of 501 people per square mile. The CCD covers the zip codes 78733, 78734, 78736, 78737, and 78738, and includes the cities of Lakeway and Bee Cave, the unincorporated communities of Hudson Bend and Volente along the lake, the Westlake corner of Eanes ISD, the older neighborhoods of Oak Hill, and the western edge of the Lake Travis ISD attendance zones.

The population is older, wealthier, and more educated than the broader Austin metro. Median age is 44.8, about 25 percent higher than the Travis County figure of 35.6 and roughly 9 years above the Austin MSA median of 36. Persons per household average 2.4, slightly above the Travis County figure of 2.2, with an unusual combination of long-tenured retirees and well-resourced young families forming the household mix. Among women aged 15 to 50, 5.9 percent gave birth in the past year, about 1.4 times the Travis County rate of 4.4 percent. Median household income is $140,390, about 1.4 times the Travis County figure of $99,611 and roughly 1.4 times the Austin MSA median of $100,431. Per capita income is $86,442, about 1.4 times the county figure of $62,607 and well over double the Texas figure of $40,752. The median value of an owner-occupied home is $756,400, about 1.5 times the Travis County figure of $523,000 and roughly 1.6 times the MSA's $465,000. The CCD is also notably stable for a Greater Austin region. Only 11.6 percent of residents moved in the past year, about three-fifths of the Travis County rate of 18.7 percent, which means the families and households named in this guide largely stay put.

Race and ethnicity in Southwest Travis run substantially more White and less Hispanic than the MSA as a whole. Non-Hispanic White residents are 71.3 percent of the population, Hispanic or Latino residents are 15.1 percent, Non-Hispanic Asian residents are 7.3 percent, residents of two or more races are 3.6 percent, and Non-Hispanic Black residents are 2.3 percent. Foreign-born residents are 12.8 percent of the population, about two-thirds of the Travis County figure of 18.1 percent and below the MSA's 15.4 percent. Veterans are 5.5 percent of the adult civilian population, about 25 percent above the Travis County figure of 4.4 percent. The bachelor's degree or higher attainment rate is 66.2 percent, about 20 percent higher than the Travis County figure of 56.6 percent and nearly double the United States rate of 35.7 percent. The poverty rate is 5.7 percent, about half the Travis County rate of 10.9 percent and roughly half the MSA rate of 9.8 percent. Mean travel time to work is 27.5 minutes, very close to the MSA average of 27.3 minutes, with the bulk of commuters traveling east toward downtown, the central business district, and the North Austin tech corridor. All figures in this section are from the 2024 five-year ACS release.

What makes this division distinct

Among the fifteen CCDs in the Greater Austin MSA, Southwest Travis is the wealthiest, most educated, and most stable. It is also one of the two oldest by median age, alongside Dripping Springs and Wimberley. The deltas tell the story. Median age is 44.8, compared with the MSA median of 36. Median household income is $140,390, up from $100,431 metro-wide. Median home value is $756,400, well above the MSA's $465,000. Bachelor's degree attainment is 66.2 percent, nearly double the United States rate of 35.7 percent and well above the metro figure. The poverty rate is 5.7 percent, about half the MSA rate of 9.8 percent. The Hispanic population share of 15.1 percent is below the metro figure of 32.2 percent. The composite portrait is of a CCD whose households are not chasing affordability or accelerating with the growth pulse of the broader region, but settling into a Hill Country corridor whose lake views, schools, and home values are reasons enough to stay.

The character of this CCD is shaped as much by the land and water as by the people. Lake Travis, the limestone canyons of the Pedernales, the cedar-and-live-oak ridges of Oak Hill, and the dolomite cliffs above Spicewood form a setting that has long attracted residents seeking distance from the urban core without distance from its economic engine. Lake Travis ISD and Eanes ISD anchor much of the region's family decision-making, and their academic reputations are a draw both for families with school-age children and for downsizing households who choose to remain near grandchildren. Bee Cave's commercial growth around the Hill Country Galleria and Highway 71, Lakeway's older lakefront neighborhoods, the Westbank pocket of Eanes, and the Oak Hill ridge each carry distinct local cultures, and the historic farming communities along RM 1826 still hold the agricultural memory of a region that was rural well within living memory.

What is most distinctive about Southwest Travis from a kingdom perspective is the combination of resources and density. The CCD has more disposable income, more educated leadership, more philanthropic capacity, and more stability per square mile than almost any other corner of the metro, yet it carries a per-capita church ratio that would be unremarkable in central Austin. Several of the most notable mission-sending nonprofits in the metro originate here, with global reach into the 10/40 Window of Africa and Asia. The pattern, in other words, is that the gospel is being sent from this CCD to the nations even where it is not yet saturating the homes and hill country roads of the CCD itself.

Church density and the mission need

Research on gospel saturation suggests that church density is a meaningful proxy for a region's spiritual health. In his book Center Church, Tim Keller notes that a region with one church per 10,000 people sees roughly 1 percent of residents attending regularly. At one church per 1,000 people, that figure rises to 15 to 20 percent, and at one per 500, more than 40 percent attend.

These numbers matter because of what tends to happen in populations. One rough model of this, the diffusion of innovation, describes a kind of tipping point. An idea often struggles to be accepted until somewhere around 16 percent of a population has taken it up, after which it can begin to sustain and spread on its own. The analogy to the gospel is inexact, and the human heart is not a product to be adopted, so we hold the model loosely. But the concept is worth consideration and used often in gospel movements around the world. A region where regular gospel engagement sits far below that threshold may simply lack the critical mass for a movement to take hold, while a region approaching it has the numeric reality from which one can grow. When compared with Keller's ratios, church density becomes a rough way of asking whether a region sits above or below that line, and gives us a guide to how we can pray.

Southwest Travis has 25 active churches (figure from the July 2026 edition) serving approximately 86,480 residents, for a ratio of roughly 1 church per 3,459 residents (figure from the July 2026 edition), one of the thinner densities in the metro. By the Keller benchmarks, this is a saturation level closer to the urban core than to the suburban Williamson County divisions, despite the CCD's stability and wealth. Several of those 25 congregations (figure from the July 2026 edition) carry too little public information to be known well, so the count says more about presence than about health. The mission need here is therefore not the absence of churches so much as the gap between a population that can afford anything and a per-capita density that suggests fewer than one in five residents is in a regular worshiping community. We believe the primary needs in Southwest Travis are threefold. First, the wealth, education, and self-sufficiency of this CCD make practical atheism and functional secularism a quieter but steadier pull than they are elsewhere in the metro, and the established churches in Lakeway, Bee Cave, and Oak Hill need ongoing renewal so that comfort does not flatten conviction. Second, the planting momentum of the last decade, with five new congregations begun since 2014, needs both reinforcement and direction so that the new works are not concentrated only on the Lakeway side and so that the Oak Hill, RM 1826, and Eanes corridors receive their share of new gospel presence. Third, the Spanish-speaking and Asian households of this CCD are real and growing, but only one Spanish-language congregation appears in the Greater Austin Mission Society research and no Asian-American or multilingual congregation is yet planted here, and we believe the Lord is preparing both to come.

A kingdom ecosystem

And yet the church was never meant to carry the whole work alone, and the nonprofits and Christian institutions listed on this page are evidence of it. A region is rarely reached by strong congregations acting in isolation. The same Tim Keller whose density research framed the mission need earlier in this guide also described, in Center Church, what he called a gospel ecosystem, the observation that lasting gospel movements grow not from isolated churches but from a whole interdependent web of gospel work in which churches and the ministries around them each supply something the others need. At the center of that ecosystem are two movements the church herself carries, the planting of new congregations and the renewal of existing ones. Around them grows a wider set of callings that no single church can hold on its own: intercession that keeps the whole work dependent on God, evangelism to those the church has not yet reached, mercy and justice among the poor and vulnerable, faith and work that sends disciples into every corner of the economy, Christian institutions like schools that form the next generation, and leadership development that raises up the pastors and planters still to come.

None of this becomes a movement, though, until the leaders carrying these callings actually know and trust one another. The connective tissue of a kingdom ecosystem is relational, pastors and ministry leaders across traditions who pray together, share what they are learning, and labor toward a common mission rather than guarding their own corner. Where that trust is real, the parts begin to feed one another, and where it is absent, even well-resourced ministries work at cross purposes. Unity here is not a program to be launched but the fruit of a shared mission held long enough for friendship to grow.

The wider Austin kingdom ecosystem

Southwest Travis does not carry the whole mission alone. Around every congregation in this CCD sits a citywide gospel ecosystem that any church here can draw on, organized below by the same Keller categories. These are metro-wide ministries whose service area is the region rather than a single division, so the names that follow are illustrative highlights rather than a full directory.

Church networks knit congregations together across the metro, among them the Austin Baptist Association and the Diocese of Austin. Intercessory ministries keep the whole work dependent on God, including the House of Intercession, HOPE Prayer Ministry, and the Lake Travis Prayer Room. Specialized evangelism is the largest category in the metro and reaches particular fields, with campus and athletic ministries like Cru City Austin, the Fellowship of Christian Athletes across every county, Campus Renewal Ministries, and Launch Global. Justice and mercy ministries carry the poor and vulnerable, among them World Relief, Habitat for Humanity Austin, Unbound Now, and Texas Alliance for Life. Faith and work ministries send disciples into the economy, including the Faith and Work Movement, Faith Driven Entrepreneurs, the National Christian Foundation Austin, and C12 Central Texas. Christian institutions steward long-term formation, such as the Texas Methodist Foundation. Leadership development raises up the next generation of pastors and planters, through the Colson Fellows Program, New Canaan Society Austin, PastorServe, and Mission Increase. And unifying networks connect leaders across congregations, traditions, and sectors for the good of the whole city, among them Christ Together Greater Austin, the Church Ambassador Network of Texas, and the Greater Austin Mission Society.

For Southwest Travis, this citywide ecosystem is a needed complement to a very thin local landscape. With the fewest churches of any CCD in the metro and the highest residents-per-church figure, the affluent lake communities of Lakeway and Bee Cave lean on the wider region for much of the specialized ministry they cannot yet sustain alone. The strengths worth building on are the crisis and broad-service mercy already rooted here, in Lake Travis Crisis Ministries and the broad-service ministries of the lake corridor, and the Lake Travis Prayer Room's place in the metro's intercession network. The clearest gaps are church planting itself and the multilingual, recovery, and youth ministries that are almost entirely absent, so the region draws on the citywide evangelism, justice, and church-planting networks even as its abundance is positioned to help fund them.
