Source identity and administrative path
The source row behind São Luís is GeoNames ID 3388368. Its recorded administrative path is Sao Luis → Maranhao → Brazil, and GeoNames classifies the place as a first-order administrative seat. São Luís 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 2026-04-13; 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, São Luís ranks 600 by recorded population. Inside the 48 selected Brazil entries it ranks 16; inside the 198 entries in its broad region it ranks 83. Its 917,237 population value is 1.21 times the 758,563 median for the country cohort and 1.12 times the 816,326 regional median. São Luís sits in the second quarter of this atlas's Brazil population cohort. São Luís's recorded value stays within one quarter of 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
São Luís's three nearest other atlas coordinates are Teresina at 329.726 km with 871,126 recorded people; Ananindeua at 470.394 km with 535,547 recorded people; Belém at 481.941 km with 1,499,641 recorded people. The closest-to-farthest distance spread is 152.215 km. Compared with Teresina, São Luís's recorded population is 1.05 times as large. Against São Luís, Teresina follows Teresina → Piaui → Brazil in the source. Its point has lower latitude and higher longitude; it belongs to the same selected Brazil cohort, uses the shared America/Fortaleza identifier, and carries the same first-order administrative seat class. Its recorded population is below São Luís's. Against São Luís, Ananindeua follows Ananindeua → Para → Brazil in the source. Its point has higher latitude and lower longitude; it belongs to the same selected Brazil cohort, uses America/Belem instead of America/Fortaleza, and carries populated place rather than first-order administrative seat. Its recorded population is below São Luís's. Against São Luís, Belém follows Belem → Para → Brazil in the source. Its point has higher latitude and lower longitude; it belongs to the same selected Brazil cohort, uses America/Belem instead of America/Fortaleza, and carries the same first-order administrative seat class. Its recorded population is above São Luís's. Its nearest-neighbor distance ranks 1,130 of 1,206 from shortest to longest in the same snapshot. São Luís'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 3388368, the coordinate pair 2.5297 / 44.3028, country rank 16 of 48, and neighbor GeoNames 3386496 at 329.726 km bind São Luís 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
São Luís's reference point is 2.5297° south and 44.3028° west. The IANA identifier America/Fortaleza is shared by 5 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. São Luís's row carries both second- and first-order administrative labels. São Luís's point falls in the near-equatorial coordinate band used by this atlas's row checks. São Luís's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for São Luís, 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.
