“Against peers” compares the change with the same change in the 14640 cities and towns that have the same two periods. It describes how common a change is, not why it happened.

Sources: American Community Survey 5-Year Estimates. Values are the latest and the one five years earlier of the same publisher dataset; datasets that changed publisher in between are never compared.

Survey estimates (American Community Survey) compare the two most recent 5-year windows that do not share years, so the margin of error of the difference holds. The 2015-2019 window predates the pandemic and 2020-2024 includes it.
A change counts only when it is larger than 1.645 times the square root of the two standard errors squared, summed (a 90% margin). Measures published without a margin must change by at least 5% to count.
“Against peers” compares the change with the same change in the 15651 cities and towns that have the same two periods. It describes how common a change is, not why it happened.
Standing is a percentile among the same places: 0 is the lowest value on the measure (or the worst when lower is better), 100 the best.

Cities and towns like Mammoth, Arizona five years ago that improved

The places whose measures looked most like those of Mammoth, Arizona in the earlier period, ranked by how many measures improved beyond the margin of error, minus how many declined. A comparison of published data, not a forecast and not advice.

For comparison, Mammoth, Arizona itself moved −1 points in standing on average over the same 7 measures (standings of all places average about zero).

How the ranking works

Similarity is the root-mean-square difference of standings in the earlier period over the measures most places have. Places are ranked by measures that improved beyond the margin of error minus those that declined (a count that estimation noise in small places cannot inflate), then by the mean change of standing over the measures a place has in both periods. Only places with more improvements than declines and a rise in standing are listed. Standings are relative, so a place can improve in absolute terms and still lose standing.

Local businesses

Employer businesses and sole proprietors by industry, per resident and against the state and the nation. Counts of businesses next to counts of people, not a measure of demand.

The Census Bureau publishes business counts by county, not by city, so these are the figures of Pinal County, the county holding most of Mammoth's residents.

Pinal County has 4,723 employer establishments, 97.1 for every 10,000 residents (0.39× the US rate of 248; 0.44× Arizona's), with 63,258 paid employees at an average annual pay of $50,659. The Census Bureau also counts 31,956 nonemployer businesses, mostly sole proprietors.

How this is estimated

Agencies report each contract action's place of performance as a county and a ZIP code. A ZIP code's money is split among the cities it covers by the share of its land inside each (Census 2020 ZIP code tabulation areas); the part outside city limits stays with the county.

The place of performance is what the contracting agency reports, often the contractor's office rather than where the work happens.
Shares are of land, not of people or businesses: a ZIP code that is mostly rural land but has its offices in town gives the town less than it should.
ZIP codes that are not mapped areas (post office boxes, the unique ZIP codes of large federal sites and companies) stay with their county, unless one city covers nearly all of it.
Counts of actions and awards include those only partly in Mammoth, Arizona, so they do not add up across cities.

Mammoth, Arizona's figures are part of those of Pinal County, AZ ($56.5M in FY2026), never added to them: 0.0% of that total.

Grants and other federal assistance are counted by county here, not split among cities: Mammoth is mostly in Pinal County.
