Source identity and administrative path
The source row behind Ludhiana is GeoNames ID 1264728. Its recorded administrative path is Ludhiana → Punjab → India, and GeoNames classifies the place as a populated place. Ludhiana 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 2025-12-15; 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, Ludhiana ranks 278 by recorded population. Inside the 109 selected India entries it ranks 23; inside the 632 entries in its broad region it ranks 161. Its 1,618,879 population value is 1.62 times the 1,001,694 median for the country cohort and 1.61 times the 1,008,426 regional median. Ludhiana falls between the leading tenth and quarter of this atlas's India population cohort. Ludhiana's recorded value is above the country-cohort median but remains below twice that benchmark. These comparisons describe this selected dataset only; they are not current census rankings or official urban-area boundaries.
Nearest-reference pattern
Ludhiana's three nearest other atlas coordinates are Jalandhar at 52.893 km with 868,929 recorded people; Chandigarh at 91.358 km with 970,602 recorded people; Amritsar at 122.009 km with 1,159,227 recorded people. The closest-to-farthest distance spread is 69.116 km. Compared with Jalandhar, Ludhiana's recorded population is 1.86 times as large. Against Ludhiana, Jalandhar follows Jalandhar → Punjab → India in the source. Its point has higher latitude and lower longitude; it belongs to the same selected India cohort, uses the shared Asia/Kolkata identifier, and carries the same populated place class. Its recorded population is below Ludhiana's. Against Ludhiana, Chandigarh follows Chandigarh → India in the source. Its point has lower latitude and higher longitude; it belongs to the same selected India cohort, uses the shared Asia/Kolkata identifier, and carries first-order administrative seat rather than populated place. Its recorded population is below Ludhiana's. Against Ludhiana, Amritsar follows Amritsar → Punjab → India in the source. Its point has higher latitude and lower longitude; it belongs to the same selected India cohort, uses the shared Asia/Kolkata identifier, and carries the same populated place class. Its recorded population is below Ludhiana's. Its nearest-neighbor distance ranks 461 of 1,206 from shortest to longest in the same snapshot. Ludhiana's nearest-coordinate gap sits in the second quarter 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 1264728, the coordinate pair 30.9120 / 75.8538, country rank 23 of 109, and neighbor GeoNames 1268782 at 52.893 km bind Ludhiana 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
Ludhiana's reference point is 30.9120° north and 75.8538° east. The IANA identifier Asia/Kolkata is shared by 109 city rows in this catalog, while the GeoNames class PPL is shared by 243 rows. Ludhiana's row carries both second- and first-order administrative labels. Ludhiana's point falls in the middle-latitude coordinate band used by this atlas's row checks. Ludhiana's time-zone field defines the narrower catalog cohort; its place class is shared more broadly. GeoNames supplies no elevation for Ludhiana, 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.
