Source identity and administrative path
The source row behind Pingdu is GeoNames ID 1798821. Its recorded administrative path is Qingdao Shi → Shandong → China, and GeoNames classifies the place as a third-order administrative seat. Pingdu 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 2022-04-01; 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, Pingdu ranks 1,036 by recorded population. Inside the 296 selected China entries it ranks 272; inside the 632 entries in its broad region it ranks 552. Its 542,234 population value is 0.47 times the 1,165,375 median for the country cohort and 0.54 times the 1,008,426 regional median. Pingdu sits in the lower half of this atlas's selected China entries. Pingdu'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
Pingdu's three nearest other atlas coordinates are Jiaozhou at 55.891 km with 619,266 recorded people; Weifang at 75.693 km with 2,044,028 recorded people; Qingdao at 88.937 km with 7,172,451 recorded people. The closest-to-farthest distance spread is 33.046 km. Compared with Jiaozhou, Pingdu's recorded population is 0.88 times as large. Against Pingdu, Jiaozhou follows Qingdao Shi → Shandong → China in the source. Its point has lower latitude and higher longitude; it belongs to the same selected China cohort, uses the shared Asia/Shanghai identifier, and carries the same third-order administrative seat class. Its recorded population is above Pingdu's. Against Pingdu, Weifang follows Weifang Shi → Shandong → China in the source. Its point has lower latitude and lower longitude; it belongs to the same selected China cohort, uses the shared Asia/Shanghai identifier, and carries populated place rather than third-order administrative seat. Its recorded population is above Pingdu's. Against Pingdu, Qingdao follows Qingdao Shi → Shandong → China in the source. Its point has lower latitude and higher longitude; it belongs to the same selected China cohort, uses the shared Asia/Shanghai identifier, and carries second-order administrative seat rather than third-order administrative seat. Its recorded population is above Pingdu's. Its nearest-neighbor distance ranks 481 of 1,206 from shortest to longest in the same snapshot. Pingdu'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 1798821, the coordinate pair 36.7844 / 119.9464, country rank 272 of 296, and neighbor GeoNames 1806096 at 55.891 km bind Pingdu 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
Pingdu's reference point is 36.7844° north and 119.9464° east. The IANA identifier Asia/Shanghai is shared by 291 city rows in this catalog, while the GeoNames class PPLA3 is shared by 60 rows. Pingdu's row carries both second- and first-order administrative labels. Pingdu's point falls in the middle-latitude coordinate band used by this atlas's row checks. Pingdu's place-class field defines the narrower catalog cohort; its time zone is shared more broadly. GeoNames supplies no elevation for Pingdu, 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.
