County Profile

40,743 residents. Safety, jobs, income, housing cost, climate and natural-hazard risk for St. John the Baptist 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.

The quick read

Employment conditions sit below most comparable published profiles: unemployment is 5.9% and the Opportunity signal places St. John the Baptist Parish in the bottom 21%.

Residential permitting has slowed: 44 units authorized over the past twelve months, 28% below the prior year.

Physical-risk exposure is above the national median, driven mainly by hurricane, inland flooding and coastal flooding.

Each point is a separate five-year estimate, most recently $66,630 in the 2024 ACS 5-Year. Consecutive releases share four years of sample, so AreaProfile shows them as a record of successive estimates and does not compute a year-over-year change from them.

79.7% 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 $1,334 takes 24% of median household income, below the 30% threshold at which a household is considered cost-burdened.

A median home costs 2.9 times median household income here, close to the historic benchmark for an affordable market.

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.

Permitting is broadly steady, measured from 2020 to 2025.

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 fallen 6% since 2020, reaching 39,694 in 2024.

New construction is predominantly single-family: only 0% of permitted units are in buildings of five or more homes.

At 1.1 permitted units per 1,000 residents, building activity is below 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 46°F.

Normal annual precipitation is 63.3 inches.

Air quality measures a median index of 36, in the Good band, and about 2 days a year pass 100, the threshold at which the air is unhealthy for sensitive groups.

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

34 / 100
Physical resilience

The hazards accounting for most of this area's expected annual loss are hurricane, inland flooding and coastal flooding.

HurricaneHigh
DroughtModerate
Coastal floodingElevated
LightningModerate
Inland floodingModerate

Low or minimal exposure: tornado, heat wave, cold wave, hail, ice storm, earthquake, winter weather, strong wind, wildfire, 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.

These are deaths, not offences. AreaProfile does not publish reported crime, and this is not a substitute for it — it says nothing about burglary, theft or assault.

St. John the Baptist Parish records 14.0 homicide deaths per 100,000 residents a year, higher than most counties measured. The CDC does not publish this below county level.

Firearm deaths of all intents run at 18.4 per 100,000 — more than the homicide rate, because nationally most firearm deaths are suicides.

Drug overdose deaths run at 20.6 per 100,000 residents in St. John the Baptist 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. John the Baptist 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. John the Baptist Parish rather than St. John the Baptist 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
The FBI’s Crime Data Explorer is the only source for reported offences with national coverage and a published method, and it requires an API key AreaProfile does not hold. Arrest counts, news volume and commercial “safety scores” are not substituted in the meantime. What is published above under Safety is a different measurement — deaths rather than offences, from death certificates rather than police returns — and it covers no property crime at all.
Taxes
No tax dataset has met the source admission test for coverage, transparent methodology and update cadence. Nothing here is individualized tax advice.
Full cost of living
No public source publishes one with national coverage and a documented method. 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.

Access
