I am doing a research project and would like to access Russian census data from 2010 that is broken down by region but I do not speak Russian. Does anyone know if this data is available in English? The 2010 data is available here in Russian: https://www.gks.ru/free_doc/new_site/perepis2010/croc/perepis_itogi1612.htm
I've only seen this data in Russian, unfortunately. From 2010, you can find census population data on Wikipedia but it's also in Russian. The link is here. Note that you can try the English translation of this page by clicking the English link under Languages header in the left sidebar.
If you need help with translation of titles of regions, please do not hesitate to contact me.
