How this community compares with the United States

State-context comparisons use the same source period and composition schema. National community averages should not be treated as characteristics of any person.

The U.S.–Czechia community contains materially different racial, ethnic, generational, linguistic, geographic, household, and socioeconomic profiles. National averages should not be treated as characteristics of every person.

Closest demographic peers

Peer rankings use population and settlement, migration, race and ethnicity, age and household, education and economic structure, language, and housing as separately disclosed dimensions.

Data quality

Profile state: eligible_high_reliability
Reliable dimensions: 19
Observed basis: Country of birth in the 2020–2024 ACS 5-year PUMS

Suppressed cells remain labeled. Missing values and shared zeroes do not create similarity.

What should not be inferred

Aggregate demographic similarity does not establish agreement, alliance, representation, consent, endorsement, political behavior, nationality, dual citizenship, religion, caste, tribe, sect, or individual identity.

How the comparison was calculated

Dimension-specific categorical distributions use square-root Jensen–Shannon distance; ordered distributions use bounded Wasserstein distance; population totals use log-scaled distance; and state footprints use Jensen–Shannon distance. Available reliable dimensions are combined with versioned weights. KNN is a retrieval method, not a public claim about alliance.
