million. According to demographic studies, life expectancy, which had been in the high forties to low fifties, fell sharply for those born in 1932 to 28 years, and for 1933 fell further to the extremely low 10.8 years for females and 7.3 years for males. It remained abnormally low for 1934 but, as commonly expected for the post-crisis period peaked in 1935–36. According to historian Snyder in 2010, the recorded figure of excess deaths was 2.4 million. However, Snyder claims that this figure is "substantially low" due to many deaths going unrecorded. Snyder states that demographic calculations carried out by the Ukrainian government provide a figure of 3.89 million dead, and opined that the actual figure is likely between these two figures, approximately 3.3 million deaths to starvation and disease related to the starvation in Ukraine from 1932 to 1933. Snyder also estimates that of the million people who died in the Russian Soviet Federative Socialist Republic from famine at the same time, approximately 200,000 were ethnic Ukrainians due to Ukrainian-inhabited regions being particularly hard hit in Russia. As a child, Mikhail Gorbachev, born into a mixed Russian-Ukrainian family, experienced the famine in Stavropol Krai, Russia. He recalled in a memoir that "In that terrible year [in 1933] nearly half the population of my native village, Privolnoye, starved to death, including two sisters and one brother of my father." Wheatcroft and R. W. Davies concluded that disease was the cause of a large number of deaths: in 1932–1933, there were 1.2 million cases of typhus and 500,000 cases of typhoid fever. Malnourishment increases fatality rates from many diseases, and are not counted by some historians. From 1932 to 1934, the largest rate of increase was recorded for typhus, commonly spread by lice. In conditions of harvest failure and increased poverty, lice are likely to increase. Gathering numerous refugees at railway stations, on trains and elsewhere facilitates the spread. In 1933, the number of recorded cases was 20 times the 1929 level. The number of cases per head of population recorded in Ukraine in 1933 was already considerably higher than in the USSR as a whole. By June 1933, the incidence in Ukraine had increased to nearly 10 times the January level, and it was much higher than in the rest of the USSR. Estimates of the human losses due to famine must account for the numbers involved in migration (including
