Strengths · Weaknesses
Indicators where Tripoli, Iowa ranks highest and lowest among US cities and towns (score = percentile, 100 = best). Values marked “Bremer County value” are the county’s: the source publishes no figure for this city or town, and the county holding most of its residents stands in.
How each measure moved between two periods about five years apart, read against whether more or less is better, the published margin of error and the same change in other places.
Cities and towns like Tripoli, Iowa five years ago that improved
The places whose measures looked most like those of Tripoli, Iowa 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.
Who lives here
Age, race and education of residents, from the American Community Survey. Shares are of all residents (age), residents of every origin (race) or adults 25 and over (education).

Who owns and who rents, what homes cost, and what the housing stock looks like.
Getting to work
How workers travel to their job and how long it takes them.
Jobs and pay
What the largest occupations here pay, from the Bureau of Labor Statistics' Occupational Employment and Wage Statistics survey.
The Bureau of Labor Statistics publishes pay by metro area, not by county or city. The metro area page lists its largest occupations and lets you look up any job.
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.
Federal contracts performed here

“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.
For comparison, Tripoli, Iowa itself moved +5.9 points in standing on average over the same 8 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.

The Census Bureau publishes business counts by county, not by city, so these are the figures of Bremer County, the county holding most of Tripoli's residents.
Bremer County has 552 employer establishments, 218 for every 10,000 residents (0.88× the US rate of 248; 0.84× Iowa's), with 8,178 paid employees at an average annual pay of $49,318. The Census Bureau also counts 1,810 nonemployer businesses, mostly sole proprietors.

Employer establishments, employees, average pay and nonemployers of Bremer County by industry, with the density per resident against the nation
County Business Patterns (2023); Nonemployer Statistics (2024)
Per-resident figures divide by the population estimate of 2023: 25,337 residents here, 336,755,052 in the United States. County Business Patterns counts establishments in 2023; the Nonemployer Statistics count businesses in 2024.
“More than typical” is a density at least 1.25 times the nation's per resident, “fewer” at most 0.8 times, with at least 10 establishments. It compares counts of businesses with counts of people: it says nothing about demand, incomes, size, quality or profit, and visitors and commuters are not residents.
The Census Bureau adds noise to employment and payroll to protect confidentiality, and withholds some figures: an industry with few establishments can show employees or pay as unavailable.
Industries overlap: a narrower industry (full-service restaurants) is part of a broader one (restaurants), so the rows do not add up.
Industries follow the North American Industry Classification System; the two surveys use different editions (NAICS 2017 and 2022), which this page matches industry by industry.
