Source identity and administrative path
The source row behind Pekanbaru is GeoNames ID 1631761. Its recorded administrative path is Kota Pekanbaru → Riau → Indonesia, and GeoNames classifies the place as a first-order administrative seat. Pekanbaru 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 2026-06-10; 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, Pekanbaru ranks 459 by recorded population. Inside the 29 selected Indonesia entries it ranks 14; inside the 632 entries in its broad region it ranks 268. Its 1,167,599 population value is 1.00 times the 1,166,066 median for the country cohort and 1.16 times the 1,008,426 regional median. Pekanbaru sits in the second quarter of this atlas's Indonesia population cohort. Pekanbaru'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
Pekanbaru's three nearest other atlas coordinates are Padang at 202.95 km with 942,938 recorded people; Malacca at 206.771 km with 579,000 recorded people; Iskandar Puteri at 261.394 km with 575,977 recorded people. The closest-to-farthest distance spread is 58.444 km. Compared with Padang, Pekanbaru's recorded population is 1.24 times as large. Against Pekanbaru, Padang follows Kota Padang → West Sumatra → Indonesia in the source. Its point has lower latitude and lower longitude; it belongs to the same selected Indonesia cohort, uses the shared Asia/Jakarta identifier, and carries the same first-order administrative seat class. Its recorded population is below Pekanbaru's. Against Pekanbaru, Malacca follows Melaka Tengah → Melaka → Malaysia in the source. Its point has higher latitude and higher longitude; it belongs to the selected Malaysia cohort rather than Indonesia, uses Asia/Kuala_Lumpur instead of Asia/Jakarta, and carries the same first-order administrative seat class. Its recorded population is below Pekanbaru's. Against Pekanbaru, Iskandar Puteri follows Daerah Johor Baharu → Johor → Malaysia in the source. Its point has higher latitude and higher longitude; it belongs to the selected Malaysia cohort rather than Indonesia, uses Asia/Kuala_Lumpur instead of Asia/Jakarta, and carries populated place rather than first-order administrative seat. Its recorded population is below Pekanbaru's. Its nearest-neighbor distance ranks 1,005 of 1,206 from shortest to longest in the same snapshot. Pekanbaru'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 1631761, the coordinate pair 0.5167 / 101.4417, country rank 14 of 29, and neighbor GeoNames 1633419 at 202.95 km bind Pekanbaru 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
Pekanbaru's reference point is 0.5167° north and 101.4417° east. The IANA identifier Asia/Jakarta is shared by 23 city rows in this catalog, while the GeoNames class PPLA is shared by 429 rows. Pekanbaru's row carries both second- and first-order administrative labels. Pekanbaru's point falls in the near-equatorial coordinate band used by this atlas's row checks. Pekanbaru's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Pekanbaru, 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.
