St. Tammany Parish, LA
County Profile
272,421 residents. Safety, jobs, income, housing cost, climate and natural-hazard risk for St. Tammany Parish, LA.
Several figures AreaProfile publishes are measured by county and nowhere finer — death rates by intent among them. On this page those describe the geography they are printed on, which is not true of the city and ZIP pages that inherit them.
Unemployment is 4.5% and median household income $81,202, putting employment conditions in the middle range of published profiles.
1,090 housing units were authorized over the past twelve months, within 8% of the prior year — steady rather than turning.
Physical-risk exposure is above the national median, driven mainly by hurricane, inland flooding and coastal flooding.

Schools
How it’s calculated →46% of students met the state standard in mathematics and 58% in reading, across the schools here that reported results.
There are 12.9 students for every full-time teacher, fewer than in most measured places.

44.4% of students here are eligible for free or reduced-price lunch. That describes the circumstances families arrive with rather than how the schools perform, which is why AreaProfile shows it and does not score it.
Public schools only, from the NCES Common Core of Data. Schools are placed by ZIP code, so this is which schools are in this place rather than which one a particular address is zoned for — district boundaries do not follow municipal ones, and enrollment zones change. Fully virtual schools are excluded: they enroll students from across the state while reporting one administrative address, and counting them here would describe a school population this place does not have. The assessment covers grades 3 through 8, so a high school shows no proficiency figure — a dash in those columns means the test was not given at that school, not that it performed badly. Proficiency is measured against Louisiana’s own standard, so it compares cleanly within the state and only broadly against other states; AreaProfile therefore ranks it within state. The directory is current, while the proficiency figures are from the last school year with national coverage before the pandemic interrupted testing.
Housing & affordability
How it’s calculated →Median rent of $1,332 takes 20% of median household income, below the 30% threshold at which a household is considered cost-burdened.
A median home costs 3.5 times median household income here, above the historic benchmark of about three times income.
| Metric | Value | Compared nationally | Source period |
|---|---|---|---|
| Home price to income | 3.50 | Top 31%of 3,219 | 2024 ACS 5-Year |
| Homeownership rate | 78.9% | Top 25%of 3,222 | 2024 ACS 5-Year |
| Housing units ±77 | 113,911 | Top 8%of 3,222 | 2024 ACS 5-Year |
| Median gross rent ±$35 | $1,332 | Top 12%of 3,216 | 2024 ACS 5-Year |
| Median home value ±$5,856 | $284,000 | Top 22%of 3,219 | 2024 ACS 5-Year |
| Rent as a share of income | 19.7% | Top 23%of 3,216 | 2024 ACS 5-Year |
| Vacancy rate | 7.8% | Bottom 18%of 3,222 | 2024 ACS 5-Year |
Both affordability measures come from the same ACS release as the income they are compared with, so the comparison is like for like. They describe housing cost against local earnings and are not a cost-of-living index — transport, groceries, healthcare, insurance and taxes are not included, and a place can look affordable here and still be expensive to live in for reasons this does not capture.
Growth & development
How it’s calculated →An AreaProfile calculation combining permit volume per resident, its direction over one and three years, population change and employment growth. Permit volume alone is not the measure.
Population has grown 5% since 2020, reaching 277,615 in 2024.
Population is still rising, but more slowly than in the preceding year.
New construction is predominantly single-family: only 0% of permitted units are in buildings of five or more homes.
At 4.0 permitted units per 1,000 residents, building activity is above the median for measured US locations.
Weather & climate
7 of the twelve months have a normal average temperature between 55°F and 80°F. July averages a high of 91°F and January a low of 41°F.
Normal annual precipitation is 61.9 inches.
Air quality measures a median index of 39, in the Good band, and one day a year passes 100, the threshold at which the air is unhealthy for sensitive groups.
| Metric | Value | Source period |
|---|---|---|
| 90th percentile air quality index | 57.0 | 2024 calendar year |
| Annual precipitation | 61.9" | 1991-2020 Normals |
| Average January low | 41°F | 1991-2020 Normals |
| Average July high | 91°F | 1991-2020 Normals |
| Comfortable months | 7 | 1991-2020 Normals |
| Days above AQI 100 | 1 | 2024 calendar year |
| Median air quality index | 39.0 | 2024 calendar year |
| Seasonal temperature swing | 31°F | 1991-2020 Normals |
A comfortable median and a bad tail are different problems. Wildfire smoke and summer ozone show up in the worst tenth of days, not in the middle of the year.
Climate figures are thirty-year normals, not current conditions. They describe what a typical year looks like rather than what the weather is doing today. Air quality is measured rather than modelled, by EPA monitors, and published by county only where a monitor sits — roughly half the counties AreaProfile publishes have one, and the rest show nothing rather than an estimate. Air masses are regional, so a county reading describes the air over a place reasonably well, but it is still the county reading.
Physical risk
The hazards accounting for most of this area's expected annual loss are hurricane, inland flooding and coastal flooding.
Low or minimal exposure: heat wave, lightning, cold wave, wildfire, hail, tornado, strong wind, winter weather, ice storm, earthquake, landslide.
Hazard ratings are AreaProfile calculations derived from the FEMA National Risk Index v1.20.0 (December 2025). FEMA National Risk Index county record. FEMA does not endorse this presentation. Higher physical resilience means lower exposure.
Safety
How it’s measured →These are deaths, not offences — they say nothing about burglary, theft or assault.
St. Tammany Parish records 4.4 homicide deaths per 100,000 residents a year, near the middle of counties measured. The CDC does not publish this below county level.
Firearm deaths of all intents run at 16.0 per 100,000 — more than the homicide rate, because nationally most firearm deaths are suicides.
Drug overdose deaths run at 20.7 per 100,000 residents in St. Tammany Parish.
Firearm deaths count every intent together, and nationally the majority are suicides rather than homicides. The two columns overlap and should not be added.
Age-adjusted rates from provisional death certificate records, published by the CDC for St. Tammany Parish as a whole — these rates are not published below county level. A county can hold both a dense city centre and a suburb whose experience of it is nothing alike, so this describes the county around St. Tammany Parish rather than St. Tammany Parish itself. That is why AreaProfile shows these figures and does not put them in the Area Score. Where fewer than ten deaths were recorded the count is suppressed at source, and a rate built on single figures moves sharply between releases. What this measure has that reported crime does not: a death certificate is filed whether or not the local police agency submitted a return that year, so the figures stay comparable between places and over time.
What this profile does not cover
Three things people look for are missing from every AreaProfile page, and each is missing for a reason rather than by oversight. The Area Score is calculated without them and the weighting is documented on the methodology page.
- Reported crime
- Offences reported to police are published by department rather than by town, and only where a department reported every month of the year. No municipal department reports for this place — many smaller communities are policed by the county — so there is no figure to show. A partial year is never scaled up to look complete, and arrest counts or news volume are never substituted for it.
- Taxes and full cost of living
- No public source publishes either with national coverage and a method open enough to check. Housing affordability above is computed from published rent, price and income, and excludes transport, groceries, healthcare, insurance and taxes — commuting cost in particular tends to offset suburban housing savings. Nothing here is individualised tax advice.
- Anything about a specific address
- Every figure describes an area, not a street or a house. School attendance zones, insurance pricing and the character of a neighbourhood all vary within the places measured here.
Access
2 major airports lie within 100 miles, the nearest 30 miles away.
| Airport | Code | Distance | Longest runway |
|---|---|---|---|
| Stennis Intl | HSA | 30 mi | 8,498 ft |
| Louis Armstrong New Orleans Intl | MSY | 34 mi | 10,104 ft |
| Mobile Rgnl | MOB | 104 mi | 8,502 ft |
Airport identity, position and runway data come from the FAA. “Major airport” is an AreaProfile classification — a public-use civil airport with a paved runway of at least 8,000 feet — not an FAA hub designation. Distances are straight-line, not driving distance.
