The narrowest step from Very Low to Low in the dataset

The Low row is shared across 19 states; the row above it is not

Divide the four-person Low Income figure by the Very Low Income figure above it and this page returns 1.25. Across all 4,764 records that multiple is the smallest published, and this record is its only holder. Just 21 records come in under 1.30, while 2,389 sit at 1.60 or above, 1,032 of them landing on 1.60 exactly.

The rows do not behave alike, and that is what the step is measuring. The Low row here is not local to Los Alamos at all — every figure in it, $74,800 for a one-person household through $141,000 for an eight-person household, is published identically by 187 of the 4,764 records, spread across 19 states. The Very Low row is local: those same 187 records carry 33 different four-person Very Low limits, from $67,000 up to the $85,450 on this page, and 30 different Extremely Low ones.

This record sits at the top of that group on both counts. Of the 187 records sharing the Low row, none has an area median family income above this page's $182,500 and none has a four-person Very Low limit above $85,450; the group's area incomes start at $111,900. So the Low row does not move across that group while the Very Low row does, and this page holds the top of both — which is where the step between them closes to its minimum. The same pattern read at the level of the limits themselves is set out on Santa Clara County, California, which reports the highest area income in the dataset and only the fifth-highest four-person Low Income limit.

One consequence is visible on the table without any arithmetic: $85,450 is printed twice, as the two-person Low Income limit and as the four-person Very Low Income limit. Exactly one record in the dataset prints those cells with the same figure, and it is this one.

Sources & methodology

HUD income limits and Fair Market Rents are taken from the fiscal-year tables HUD publishes per HUD-defined area — which can include more than one county — and joined to this county record. State comparisons are computed across the 2BR Fair Market Rents of the county records in the same state; the median uses the middle value and is not weighted by households or population, rank 1 is the highest rent in the state, and county records with identical rents share a rank.

The income figure used throughout this page is HUD's Median Family Income for the HUD area above. It is not a Census median household income and the two are not interchangeable.

The purchasing power module applies a historical CPI ratio: Adjusted = Nominal × CPI(to) / CPI(from). No interpolation is applied and missing months are not imputed; CPI-U is a historical index, not a forecast. The “STABLE” target adds a fixed +10% buffer over the local HUD Median Family Income — that buffer is a GovCalculator heuristic, not a HUD, BLS or IRS determination.

The CPI-U series is the official BLS CUUR0000SA0 index, not seasonally adjusted, taken from the published BLS series: 36 published monthly observations. Months BLS did not publish are not interpolated. IRS Publication 15-T is cited as an official reference only — no federal withholding is calculated anywhere on this site.

Verify eligibility requirements with local program administrators: household size, deductions, and program-specific definitions can materially change outcomes.
