In some cases, e.g. if no current figures are available, calculations of 禄City Population芦 are presented. If suitable definitions of urban agglomerations are missing, own demarcations are used. Please, pay attention to <strong>table footnotes</strong> as well as to <strong>tooltips</strong> that are shown over figures in italics.</p> <p>Population statistics are all of varying, and some of suspect <strong>accuracy</strong>. There are several reasons: poor currentness or accuracy of the investigation, disregarded boundary changes, errors in projections, census underenumeration and so on. 禄City Population芦 preferably presents <strong>comparable population</strong> figures. Thus, after boundary changes older population figures are – if possible – adapted to new demarcations. Population figures given for <em>apparently</em> the same place often differ because investigations (e.g., census with underenumeration or an adjusted estimate) or areas (city, settlement, urban agglomeration, metropolitan area, etc.) are different.
