Precisely enumerated population data being usually unavailable, transportation researchers generate their statistical equivalent through population synthesis. While various synthesizers are proposed to optimize the accuracy of synthetic populations, no insight is given regarding the impact of the geographic resolution on population synthesis quality. In this paper, we synthesize populations for the Census Metropolitan Areas of Montreal, Toronto, and Vancouver at various geographic resolutions using the enhanced iterative proportional updating algorithm. We define accuracy (representativeness of the sociodemographic characteristics of the entire population) and precision (representativeness of the real population\u2019s spatial heterogeneity) as metrics of synthetic populations\u2019 quality and measure the impact of the reference resolution on them. Moreover, we assess census targets\u2019 harmonization and double geographic resolution control as means of quality improvement. We find that with a less aggregate reference resolution, the gain in precision is higher than the loss in accuracy. The most disaggregate resolution is thus found to be the best choice. Harmonization proves to further optimize synthetic populations while double control harms their quality. Hence, synthesizing at the Dissemination Area resolution using harmonized census targets is found to yield optimal synthetic populations.<\/jats:p>","DOI":"10.3390\/ijgi10110790","type":"journal-article","created":{"date-parts":[[2021,11,19]],"date-time":"2021-11-19T13:29:17Z","timestamp":1637328557000},"page":"790","source":"Crossref","is-referenced-by-count":3,"title":["Impact of the Geographic Resolution on Population Synthesis Quality"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"http:\/\/orcid.org\/0000-0002-0459-5836","authenticated-orcid":false,"given":"Mohamed","family":"Khachman","sequence":"first","affiliation":[{"name":"Department of Civil, Geological and Mining Engineering, Polytechnique Montr\u00e9al, C.P. 6079, Station Centre-Ville, Montreal, QC H3C 3A7, Canada"}]},{"given":"Catherine","family":"Morency","sequence":"additional","affiliation":[{"name":"Department of Civil, Geological and Mining Engineering, Polytechnique Montr\u00e9al, C.P. 6079, Station Centre-Ville, Montreal, QC H3C 3A7, Canada"}]},{"given":"Francesco","family":"Ciari","sequence":"additional","affiliation":[{"name":"Department of Civil, Geological and Mining Engineering, Polytechnique Montr\u00e9al, C.P. 6079, Station Centre-Ville, Montreal, QC H3C 3A7, Canada"}]}],"member":"1968","published-online":{"date-parts":[[2021,11,19]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"869","DOI":"10.1016\/j.trc.2010.02.007","article-title":"Synthetic household travel survey data simulation","volume":"18","author":"Mohammadian","year":"2010","journal-title":"Transp.
