📝 How we sourced this

Population, income, and housing-cost figures come from the U.S. Census Bureau American Community Survey 5-year estimates (B-series tables). Crime data uses FBI UCR; climate uses NOAA Climate Normals; school counts come from NCES Common Core of Data; permits use the Census Building Permits Survey (BPS). See our methodology page for the full ETL pipeline and OMB / FIPS join keys.

A decision-led reading path

Useful questions to ask of Lake San Marcos's data

How this reading path is ordered

This is not a composite city score. It is a city-specific route through the available public records, ordered for this profile so the page starts with questions the joined data can actually answer. The route here runs from comparison shortlist to housing and income to work and mobility; another city can have a different sequence or fewer supported layers because the source joins are not uniform.

For Lake San Marcos, city-specific coverage includes commute-mode shares. No matched row is reported here for local building permits, within-city Census tract profiles, annual population history, FBI reported-crime rates, matched public-school count; the page leaves those layers out instead of substituting a statewide or national value.

1. Comparison shortlist

Which cities make useful reference points for Lake San Marcos?

Use the in-state set to hold state policy and broad price conditions more nearly constant. Use the nationwide size set to ask whether cities with a similar resident count produce different housing, income, or commute outcomes. The income set is a third lens, deliberately separate from population matching.

Within California, the closest population matches are Sunnyside (5,003 residents, $114,500 income); Lake of the Pines (5,012 residents, $118,661 income); Lake Wildwood (4,967 residents, $87,552 income). Outside the state, the closest population matches in this dataset are Ste. Genevieve, MO (4,996 residents); Naples Park, FL (4,995 residents); Winter Beach, FL (4,995 residents). A third, income-matched reference set of 6 out-of-state cities sits in the income neighbourhood chart near the Place Dossier plate. These are mechanical peer sets, not claims that the places share a labor market, climate, culture, or metro context.

2. Housing and income

How far does income reach against housing in Lake San Marcos?

This is a citywide price-to-income reference, not a mortgage-affordability test; it does not include interest rates, taxes, insurance, household size, or an individual buyer's down payment. Housing value is high relative to the citywide income median. That flags a question for comparison, not a verdict: tenure, household composition, financing costs, and the age of the ACS estimate can all change what a resident actually pays.

The home-value-to-income reference is comparatively stretched: the ACS median home value is 8.5 times median household income. The ACS poverty estimate is 2.5%, which keeps the citywide median from describing every household.

Compare the housing trade-off →

Question 3

What does the journey to work look like in Lake San Marcos?

Driving alone is the largest reported mode at 73.5%. A reliable mean commute time is not available for this row, so the mode shares carry the comparison.

Mode share answers how workers usually travel; it does not measure congestion, reliability, distance to a particular job, or the quality of transit service. Remote work has a visible role in the local pattern. That can reduce commute exposure for some workers, but it says nothing about job availability or broadband quality; read it alongside income and housing rather than as a stand-alone lifestyle score.

At 8.5×, Lake San Marcos sits in the pressured band: national rank #15,175 of 15,516 and #11,119 of 11,323micro cities (under 10,000). Housing value is high relative to the citywide income median, a comparison flag, not a verdict on any household.

How this ratio is calculated

Ratio = Census ACS 2023 median home value ÷ median household income for cities with both fields and population ≥ 1,000. Rank 1 = lowest ratio (most compact). Bands match the fleet affordability thresholds used on guides (<3.0 / 3.0–5.0 / >5.0). This is not a mortgage payment estimate and does not include rates, taxes, insurance, or down payment.
