If you pastor here, pray here, or have given your years to this place, this page is for you.

We count 52 active congregations in San Marcos today, and about 77,080 neighbors, which is roughly one church for every 1,480 of them. That is not a scorecard. It is a description of the ground you share, and of how much of it none of you can reach alone.

Start by praying

Before the data, before the strategy, pray. We wrote the San Marcos prayer guide to be prayed out loud with two or three others, on a rhythm, across whatever lines usually keep you apart. Bring the leaders you already know. Invite one you do not.

Portrait

The San Marcos Census County Division sits at the southern hinge of the Greater Austin MSA, a 133-square-mile region in central Hays County built around the city of San Marcos, the spring-fed San Marcos River, and Texas State University. Its population is 77,080, with a density of 579.5 people per square mile. The river that runs through the center of this CCD rises from one of the oldest continuously inhabited sites in North America, and the university that sits beside it has shaped the rhythm of the region for more than a century. To understand San Marcos demographically, you have to begin with the university, because almost every number in this CCD bends around it.

San Marcos is the youngest CCD in the entire Greater Austin metro, and it is not close. The median age is 26.4, about three-quarters of Hays County's 34.1 and roughly two-thirds of the United States median of 38.9. Texas State University enrolled a record 44,596 students in the fall of 2025, more than half the total population of this CCD, and the student body reshapes nearly every household and economic figure here. Households average just 2.3 persons per household, below the MSA's 2.5, reflecting the apartments and shared rentals that ring the campus. There are 30,445 households and 32,972 housing units. The median value of owner-occupied housing is $305,600, about three-quarters of Hays County's $399,800 and well below the MSA median of roughly $465,000, though much of San Marcos lives in rental rather than owned housing. The most striking household number is mobility. Roughly 30 percent of residents moved within the past year, more than double the Texas and national rates, the unmistakable churn of a town where tens of thousands of young adults arrive and depart on the academic calendar.

Race and ethnicity in San Marcos are nearly evenly split between two large groups. Non-Hispanic White residents are 44.7 percent of the population and Hispanic or Latino residents are 42.9 percent, a near-even balance that makes San Marcos one of the most heavily Hispanic CCDs in the metro. Non-Hispanic Black residents are 4.9 percent, residents of two or more races are 3.7 percent, Non-Hispanic Asian residents are 1.9 percent, and Non-Hispanic residents of some other race are 1.8 percent. Foreign-born residents are 8.9 percent of the population, about half the MSA figure of 16.2 percent. The Hispanic presence in San Marcos is not primarily an immigrant story. It is the deep Tejano inheritance of the old Camino Real and the San Marcos River valley, layered with the Spanish-speaking families who have lived in this part of Hays County for generations.

Economically, San Marcos reads as a college town, which means its numbers require interpretation. Per capita income is $28,230 and median household income is $51,139, both roughly three-fifths of the Hays County figures and about half the MSA median of $100,431. The poverty rate is 25.9 percent, more than double the Hays County rate of 12.1 percent and the highest of any CCD in the Greater Austin metro. A large share of that figure is the statistical poverty of students who report little income while enrolled, and it should not be read as straightforward economic distress. Yet the number also conceals genuine and lasting need among the non-student families of San Marcos, who live alongside a transient student majority in one of the more expensive housing markets in Central Texas. Educational attainment is high by some measures and complicated by others. High school completion is 89.3 percent, and bachelor's degree attainment is 36.8 percent, below the metro rate of 45 percent, a figure depressed by the very students who will earn degrees but have not yet. Mean travel time to work is 24.6 minutes, shorter than the MSA average of 27.3, because in San Marcos a large portion of the population lives, studies, and works inside the same CCD rather than commuting out. 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, San Marcos is the university CCD, and that single fact distinguishes it from every other division in the metro. No other CCD is built around a campus of more than 44,000 students. Compared to its sister CCD of Kyle and Buda directly to the north, San Marcos is far younger, poorer on paper, denser in rental housing, and dramatically more transient, even though the two share Hays County and the same I-35 corridor. Compared to Austin proper, San Marcos is younger, more Hispanic, less affluent, and more concentrated around a single dominant institution. Compared to the Hill Country CCD of Dripping Springs and Wimberley to the west, San Marcos could hardly be more different, trading rolling ranchland and retirement-age affluence for a young, churning, working-class college town on the river.

The deltas from the MSA tell the story. Median age is 26.4, well below the metro's 36 and the lowest of any CCD in Greater Austin. The poverty rate is 25.9 percent, compared with 9.8 percent across the MSA, the highest in the metro. Per capita income is $28,230, far below the metro level. Residential mobility runs near 30 percent in a single year, compared with the low double digits regionally. Persons per household are 2.3, below the MSA's 2.5. Hispanic population share is 42.9 percent, up from 32.2 percent across the metro. Foreign-born share is 8.9 percent, well below the MSA's 16.2 percent. Mean commute is 24.6 minutes, below the metro's 27.3, because San Marcos workers stay closer to home than almost any other CCD in the region. The composite portrait is of a CCD unlike any other in Greater Austin, a young, Hispanic-and-Anglo, spring-fed college town where a population the size of a mid-size city refreshes itself every four years.

San Marcos also carries a layered cultural memory that no other CCD in the metro shares. The San Marcos River and its springs have drawn people for more than ten thousand years, and the town that grew up beside them became, in time, the home of Southwest Texas State Teachers College, now Texas State University, the only Texas institution to have educated a President of the United States in Lyndon Baines Johnson, who graduated in 1930. The river still defines the town, the university still drives its economy, and the historic neighborhoods east of downtown still hold the Black and Tejano congregations that have anchored San Marcos since the years just after the Civil War. The Church here is not a single story. It is a downtown of nineteenth-century mainline sanctuaries, a ring of student-reaching plants around the campus, a thin but vital Spanish-speaking presence, and a set of historically Black congregations whose memory of San Marcos runs back to 1866.

You share San Marcos with congregations across 12 denominational families. Some of them you know. Most of them you probably do not, and that is the ordinary condition of a city, not a failure. We put the list here so you can start.

Drawing the fifteen divisions

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.

San Marcos has 48 active churches serving approximately 77,080 residents, for a ratio of roughly 1 church per 1,606 residents. On its face that is a moderate density for the Greater Austin metro. The headline number, however, hides the most important fact about this CCD. More than half the population is made up of university students who turn over every few years, who attend church at lower rates than the settled population, and who are reached, when they are reached at all, through a different kind of ministry than a neighborhood congregation. The real mission field of San Marcos is not measured in church buildings per resident. It is measured in whether the gospel reaches a rolling population of more than 44,000 young adults during the few formative years they spend on the banks of the San Marcos River. Many of the 48 active churches carry too little public information to be known well, so the count says more about presence than about health. We believe the primary missional needs in San Marcos are threefold. First, the students of Texas State need a generation of campus ministries and student-reaching churches strong enough to meet a record and still-growing enrollment. Second, in a CCD that is nearly 43 percent Hispanic, the Spanish-speaking church is strikingly thin, with only a handful of bilingual or Spanish-language congregations, and it needs both planting and strengthening. Third, the settled, non-student families of San Marcos, including the historically Black congregations near downtown and the working families across the river, need churches that see them and serve them rather than orienting everything around the university.

A kingdom ecosystem

And yet the church was never meant to carry the whole work alone, and the nonprofits and Christian institutions named just above 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

San Marcos 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 Christ Together Greater Austin, the Austin Baptist Association, the Church Ambassador Network of Texas, 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. And leadership development raises up the next generation of pastors and planters, through the Colson Fellows Program, New Canaan Society Austin, PastorServe, Mission Increase, and the Greater Austin Mission Society.

For San Marcos, the nearest strength is campus ministry, fitting for a university city where more than 44,000 students live within the CCD, and the metro's campus-evangelism networks are a resource this region can draw on directly. Almost every other locally based sector is thin, from mercy and justice to family support, so the gaps worth praying toward are wide. Pray that the churches of San Marcos would tie into the citywide campus, mercy, and church-planting networks, and that a town that mostly sends its young people out would also learn to receive the ministries that could serve the poor and the settled families who remain.
