Actually, the total number of population losses by the end of 1933 (famine death and birth deficit) across the entire Soviet Union is estimated as 6–7 million, with famine deaths in the Ukraine estimated to be about 3-3.5 million, more specifically about 3.2 million.
I believe you have to include deaths from Gulag concentration camps and deaths from disease (Typhus, etc.) made worse by malnutrition. You must also go beyond the 1932-33 time frame as the collectivization began in the 20s and was resisted all along.
