Due to very high birth rates, the proportion of Albanians increased from 75% to over 90%. In contrast, the number of Serbs barely increased, and in fact dropped from 15% to 8% of the total population, since many Serbs departed from Kosovo as a response to the tight economic climate and increased incidents with their Albanian neighbours. While there was tension, charges of "genocide" and planned harassment have been debunked as an excuse to revoke Kosovo's autonomy. For example, in 1986 the Serbian Orthodox Church published an official claim that Kosovo Serbs were being subjected to an Albanian program of 'genocide'.
