Additional Information
The problem is not reproducible in the 2025 Canada data. Minor differences exist, but they can be explained by different methods applied to the whole layer versus individual features. The differences are very minor; for the SK layer, it's 754,753 (sum of features) vs. 751,795 (whole layer). The reason for the difference: For individual features, Business Analyst Web App uses BlockApportionment with Dissemination Areas (https://pro.arcgis.com/en/pro-app/latest/help/analysis/business-analyst/data-apportionment-and-layers.htm). For the whole layer, due to the size of the dissolved feature, another method will be used: centroids of Dissemination Areas. That is the reason for this minor difference.Workaround
Block data apportionment gives expected results for the whole layer in Saskatchewan.
