Russian mobilization hitting poorer regions harder

 ISW:

... 

Russian forces reportedly continued to rush newly-mobilized men to the frontlines on October 4 and 5. Ukraine’s Center for Strategic Communications reported on October 4 that a mobilized Russian man from Orsk joined the 15th Separate Motorized Rifle Brigade to fight near Olhivka, possibly the village near Beryslav in Kherson, within five days of receiving his mobilization notice. The soldier reportedly surrendered to Ukrainian forces using Ukraine’s “I Want to Live” hotline.[54] The Donetsk People’s Republic (DNR) People’s Militia posted footage of mobilized Russian personnel training in an unspecified part of Russian-occupied Kherson Oblast on October 5 but did not clarify whether the mobilized personnel are originally from Kherson Oblast, other Russian-occupied Ukrainian territories like the DNR, or Russia itself.[55

Russian citizens who are economically disadvantaged and ethnic minority Russian communities continue to bear a disproportionate burden in mobilization rates and casualty rates according to investigative reports, suggesting that Russian authorities may be deliberately placing poor and minority Russian citizens in more dangerous positions than well-off or ethnic Russians. The Georgia-based Conflict Intelligence Team (CIT) and the Russian language outlet Important Stories released a study of mobilization numbers and mortality rate increases by Russian region on October 5, citing local officials and public media.[56] They calculated that Russian authorities have mobilized at least 213,000 men across 53 regions but were unable to find data for an additional 32 regions, suggesting that many more men have already been mobilized in the two weeks since September 21, when Russian President Vladimir Putin announced his “partial mobilization.” Defense Minister Sergei Shoigu claimed on October 4 that 200,000 men have already been mobilized.[57] CIT noted that the regions that are reporting disproportionate shares of mobilization are consistently the poorest and most majority-minority parts of Russia. Moscow and St Petersburg showed the lowest mortality rate increases since the war began, with a 0% and 3% increase respectively, whereas the Republic of Dagestan had the highest reported increase in the male mortality rate: 105%. CIT analysts suggested that the Kremlin is targeting regions that are less likely to protest disproportionate mobilization rates to generate additional manpower without increasing domestic instability.

I suspect the poorer regions are also the ones with the fewest people who can afford plane tickets and autos to flee Russia after the mobilization.   The Russians are also continuing to recruit people from their prison population.  It does appear that at least some of the mobilized troops have quickly surrendered to Ukraine forces.
