Source identity and administrative path
The source row behind Piura is GeoNames ID 3693528. Its recorded administrative path is Provincia de Piura → Piura → Peru, and GeoNames classifies the place as a first-order administrative seat. Piura occurs once as a primary city label in this atlas sample; the numeric ID remains the durable source key if names change. The city row itself was updated 2026-06-21; that date belongs to the source record, not to every transport or visitor detail in the real destination.
Population position inside fixed cohorts
Within the fixed 1,206-record atlas, Piura ranks 886 by recorded population. Inside the 6 selected Peru entries it ranks 5; inside the 198 entries in its broad region it ranks 143. Its 630,000 population value is 0.56 times the 1,131,700 median for the country cohort and 0.77 times the 816,326 regional median. Piura is rank 5 among the 6 selected Peru entries, so a percentage band would overstate this small cohort. Piura's recorded value is materially below the country-cohort median used here. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.
Nearest-reference pattern
Piura's three nearest other atlas coordinates are Chiclayo at 197.626 km with 609,400 recorded people; Cuenca at 313.976 km with 636,996 recorded people; Guayaquil at 342.843 km with 2,723,665 recorded people. The closest-to-farthest distance spread is 145.217 km. Compared with Chiclayo, Piura's recorded population is 1.03 times as large. Against Piura, Chiclayo follows Provincia de Chiclayo → Lambayeque → Peru in the source. Its point has lower latitude and higher longitude; it belongs to the same selected Peru cohort, uses the shared America/Lima identifier, and carries the same first-order administrative seat class. Its recorded population is below Piura's. Against Piura, Cuenca follows Cuenca → Azuay → Ecuador in the source. Its point has higher latitude and higher longitude; it belongs to the selected Ecuador cohort rather than Peru, uses America/Guayaquil instead of America/Lima, and carries the same first-order administrative seat class. Its recorded population is above Piura's. Against Piura, Guayaquil follows Guayaquil → Guayas → Ecuador in the source. Its point has higher latitude and higher longitude; it belongs to the selected Ecuador cohort rather than Peru, uses America/Guayaquil instead of America/Lima, and carries the same first-order administrative seat class. Its recorded population is above Piura's. Its nearest-neighbor distance ranks 988 of 1,206 from shortest to longest in the same snapshot. Piura's nearest-coordinate gap belongs to the wider half of atlas distances. This pattern can reveal whether other catalog references are geographically close, but it cannot establish whether a border crossing is possible or practical, or whether rail, road, fare, or journey-time connections exist. Read as one record signature, GeoNames 3693528, the coordinate pair 5.1819 / 80.6572, country rank 5 of 6, and neighbor GeoNames 3698350 at 197.626 km bind Piura to a reproducible comparison. That combined key distinguishes the row; it is not a recommendation or evidence of a physical connection.
Coordinate, time-zone and class cohorts
Piura's reference point is 5.1819° south and 80.6572° west. The IANA identifier America/Lima is shared by 6 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Piura's row carries both second- and first-order administrative labels. Piura's point falls in the near-equatorial coordinate band used by this atlas's row checks. Piura's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Piura, so the profile preserves that missing value instead of guessing terrain. Together these fields form a reproducible identity check for this page, not a claim about walkability, climate or accessibility.
