Quick answer
Denton County has grown to about 1.05 million residents (U.S. Census Bureau, 2024 estimate), roughly 15% more than in 2020. About 11% of working-age adults had no health insurance in the CDC's 2023 PLACES estimates, about 1 in 10 adults has diagnosed diabetes, and recent County Health Rankings data count roughly one primary care physician for every 1,850 residents. The county numbers describe the crowd — the ones that predict your health are personal: your blood pressure, your A1C, your cholesterol. Those get measured at an annual physical, often $0 with acceptable insurance.
Three questions come up at our front desk almost every week. "We just moved here — why is every doctor booked out for a month?" "My job doesn't offer insurance — am I the only one?" And: "I feel fine — do I really need a checkup?" This article answers all three with the county's own published numbers — every statistic names its source and year, because a number without a source is just a rumor with decimals.
Population: a county that added a city's worth of people
Start with the head count: the 2020 census counted 906,422 people here, and the Census Bureau's 2024 estimate puts the county at about 1,045,000 residents — growth of roughly 15% in four years, keeping Denton among Texas's fastest-growing large counties and its seventh-most populous (U.S. Census Bureau). In plain terms, the county has added about 140,000 people since 2020.
Two details inside that growth matter for health care. About 128,000 residents — roughly 12% — are 65 or older (U.S. Census Bureau, 2024), the group that uses the most primary care. And many newcomers are working-age families who land here without a local doctor — and sometimes without coverage that has caught up with the move.
Coverage: roughly 1 in 9 working-age adults is uninsured
The CDC's PLACES estimates for 2023 put the share of Denton County adults ages 18–64 with no health insurance at about 11% — roughly 1 in 9. Measured across all ages, the Census Bureau's American Community Survey put the county's overall uninsured share at about 10.6% in 2024 — on a population of about 1.05 million, that works out to on the order of 100,000 uninsured residents. Most of them are working: Census Bureau survey data show most covered residents here get a plan through an employer, so the uninsured are concentrated among part-time, gig, and contract workers, small-business staff, and people between jobs.
Context helps: in the same CDC release, Dallas County's working-age uninsured rate was about 21% — nearly double Denton's. By Texas standards this is a comparatively well-covered suburb, but the average is cold comfort to a family without a plan facing an ER bill. That is why this site is written for both readers at once — the insured patient checking a network, and the uninsured patient who needs a doctor visit with a known price. A large share of the county also buys individual coverage through the federal marketplace each fall, and a plan is only useful if your doctor is in it — at our clinic, that coverage check is free, from your insurance card, photo ID, and date of birth.
The chronic picture: quiet conditions, big numbers
The conditions that drive most health care in this county are not dramatic. They are quiet, common, and measurable:
- Diabetes: about 1 in 10 adults. The CDC's PLACES estimates for 2023 put diagnosed diabetes at roughly 10% of Denton County adults. Diabetes sits behind a large share of the county's kidney, eye, nerve, and heart problems — and it is usually manageable when it is caught early and followed regularly.
- High blood pressure: nearly 3 in 10 adults. CDC PLACES estimates published in Texas Health Resources' 2025 Community Health Needs Assessment put high blood pressure at about 29% of adults in Denton County. It has no symptoms of its own, which is why it turns up so often as a surprise finding at a routine physical — our guide to high blood pressure in Denton covers what happens next.
- Obesity: about 1 in 3 adults. The CDC's PLACES estimates for 2023 put adult obesity at roughly 34% in Denton County. Behind it sit much of the county's diabetes, joint problems, sleep apnea, and fatty liver disease.
- Mental health strain: about 1 in 6 adults. CDC PLACES figures for the county show roughly 16% of adults reporting frequent mental distress. It is part of the chronic picture, not separate from it — stress, poor sleep, blood pressure, and blood sugar feed each other.
None of these numbers is a verdict. Diabetes, blood pressure, and cholesterol are among the most treatable measurements in medicine — but only once they are measured. That is the thread connecting this section to the prevention gap below.
Access: one primary care physician for roughly every 1,850 residents
Here is the arithmetic behind the month-long wait for a new-patient appointment. County Health Rankings & Roadmaps — the University of Wisconsin Population Health Institute's annual county health data, built on the federal Area Health Resource File — has put Denton County at roughly one primary care physician for every 1,850 residents (about 1,865 to 1 in the rankings data as published in Data USA's Denton County profile), against a national figure of about 1,310 to 1 in the same rankings. Add 140,000 newcomers since 2020 to a ratio already stretched, and the result is predictable: established practices close their panels, and "we can see you in five weeks" becomes the normal answer.
The ratio is not destiny, though. It counts physicians only — modern primary care teams carry panels together — and it is a county average: your personal access depends on whether your name is already on one clinic's panel. The practical lesson is to get established before you are sick. A patient with a chart and a medication list on file gets seen faster and treated more accurately than a stranger starting from zero. New here? Our guide to setting up a doctor in your first month walks through the steps.
The prevention gap: what screening catches late
The most expensive sentence in health care is "we found it late." Texas Health Resources' 2025 Community Health Needs Assessment — its triennial study of North Texas counties, Denton included — found nearly every county it studied running below national averages for annual primary care visits and for colon cancer screening. The gap is not exotic diseases missed; it is ordinary checkups and screenings that never happen.
The national CDC figures explain why that gap matters. About 1 in 5 U.S. adults who have diabetes has not been diagnosed (CDC), and more than 1 in 3 U.S. adults has prediabetes — with more than 8 in 10 of them unaware of it (CDC). There is no reason to believe Denton County beats those national patterns: applied to our local 1-in-10 diabetes rate, they suggest thousands of neighbors have treatable blood-sugar problems a single blood test would reveal. The same logic holds for colorectal screening, which starts at age 45 — our turning-45 screening guide explains the options — and for blood pressure, which takes a cuff and two minutes to check.
What the numbers mean for one family
County statistics describe a crowd of a million. Your family's health turns on three much smaller moves:
- Put your name on one clinic's panel. In a county with roughly 1,850 residents per primary care physician, the families who get seen quickly are the ones already established somewhere. Choose one clinic, transfer your records, and let that be your first call. Our guide to choosing a primary care doctor in Denton lists what to compare.
- Book the annual physical — it is the screening net. One visit a year is where blood pressure, A1C, cholesterol, and thyroid numbers get captured before they become diagnoses. It is often $0 with acceptable insurance, or $150 self-pay with the full lab panel included at Evolve Health. Our complete guide to physicals in Denton compares every type of physical in one place.
- Know your four numbers. Blood pressure, A1C, cholesterol, and TSH explain most of what the county statistics are made of. If you have results and nobody has ever translated them, Your Numbers, Explained walks through each range in plain language.
And if your family is in the uninsured 1 in 9 right now: you are a statistic in this article and a normal patient in our clinic. A sick visit is $75 flat — in person or by video anywhere in Texas, price told before you are seen, no coverage required.
A note on the numbers themselves
Read county statistics the way you would read a weather forecast: right about the pattern, approximate about your street. Most figures here are modeled estimates, not head counts — the CDC's PLACES project, for example, builds county estimates from national survey data, and each carries a margin of error. The sources also run on different clocks: the population figures are the freshest (2024 estimates), the CDC health estimates use 2023 data published in 2025, and physician-supply snapshots lag further behind. That is why this article rounds — "about 1 in 10" instead of a decimal point — and why county averages can hide big differences between neighborhoods a few miles apart.

Frequently asked questions
How many people live in Denton County in 2026?
The most recent U.S. Census Bureau estimates put Denton County at about 1.05 million residents (2024 estimate: 1,045,120), up from 906,422 counted in the 2020 census — growth of roughly 15% in four years. That makes Denton the seventh-most populous county in Texas, and new estimates are published each spring, so the 2026 figure will not be final until the Census Bureau releases it.
How many Denton County residents don't have health insurance?
About 11% of working-age adults (ages 18–64) in Denton County had no health insurance in the CDC's PLACES estimates for 2023 — roughly 1 in 9. Across all ages, the Census Bureau's American Community Survey put the county's overall uninsured share at about 10.6% in 2024 — on a population of about 1.05 million, that works out to on the order of 100,000 residents living without coverage, most of them working adults.
How common is diabetes in Denton County?
The CDC's PLACES estimates for 2023 put diagnosed diabetes at about 10% of Denton County adults — roughly 1 in 10. That counts only people who have been told they have it. Nationally, the CDC estimates about 1 in 5 adults who have diabetes has not been diagnosed, and more than 1 in 3 U.S. adults has prediabetes, most without knowing it — which is why a simple A1C blood test is part of a regular physical.
Why can it take weeks to get a doctor's appointment in Denton County?
It is mostly math. Recent County Health Rankings data put Denton County at roughly one primary care physician for every 1,850 residents, and the county has added about 140,000 people since 2020 — appointment books fill faster than new practices open. Having your name on one clinic's panel, instead of starting from scratch each time you are sick, is the practical fix. Evolve Health offers same-day appointments, and we verify your coverage free before your visit.
What does it cost to act on these numbers at Evolve Health?
An annual physical is often $0 with acceptable insurance, or $150 self-pay with a full lab panel (blood counts, cholesterol, blood sugar, thyroid, liver, kidney, and urine tests). A sick visit is $75 flat for self-pay patients, in person or by video anywhere in Texas, with the price told before you are seen. We verify insurance coverage free from your card, photo ID, and date of birth before the visit.
Where do these numbers come from, and how current are they?
Every figure in this article comes from a named public source with its year stated: U.S. Census Bureau population estimates (2020 census and 2024 estimates), the CDC's PLACES local health estimates (2023 data), County Health Rankings & Roadmaps (University of Wisconsin Population Health Institute), and Texas Health Resources' 2025 Community Health Needs Assessment. Most are modeled estimates, not head counts, and we round them — 'about 1 in 10' rather than a decimal — because that is the honest precision of the data.
