Ruthenians at 6,000 families (6.5%). The estimate was based on the assumption that Ruthenes constituted up to a third of the population of the Khotyn county, and the rest of the recorded population was exclusively Moldavian. An alternative estimate for the same year indicates 76.4% Moldavians, 8.7% Ukrainians, 5.1% Bulgarians and Gaguzes, 4.5% Jews and 2% Russians. An 1818 statistic of three counties in southern Bessarabia (Akkerman, Izmail and Bender) that had witnessed strong emigration of the Muslim population and immigration from other regions, including Ottoman lands south of the Danube, recorded a total population of 113,835. There are conflicting figures regarding the national distribution (first figure cited by Poștarencu, second by Ungureanu): 48.64/37% Moldavians, 7.07/8.9% Russians, 15.65/17.9% Ukrainians, 17.02/21.5% Bulgarians and 11.62/14.7% others. Still in 1818, statistics for the Khotyn county in northern Bessarabia indicated 47.5% Moldavians and 42.6% Ukrainians. The Moldovan historian Ion Gumenâi records the population of Bessarabia in 1828 as 517,135, and states that 376,910 were Moldavians (72.88%), 52,000 Ruthenians (10.05%), 30,929 Jews (5.9%), 8,846 Germans (1.71%), 7,947 Russians (1.53%), 5,974 Lipovans (1.15%), 2,384 Poles (0.46%), 2,000 Greeks (0.38%), 2,000 Armenians (0.38%), and 27,445 (5.3%) settlers in the south of Bessarabia. The first statistic to record ethnic groups throughout Bessarabia was an incomplete administrative census made in 1843–1844 at the request of the Russian Academy of Sciences. The following proportions were recorded, in a total of 692,777 inhabitants: 59.4% Moldavians, 17.2% Ukrainians, 9.3% Bulgarians, 7.1% Jews, and 2.2% Russians. In the case of some urban centres, figures were not reported for all ethnic groups. Furthermore, the size of the total populations differs from other official reports of the same period, which put the population of Bessarabia at 774,492 or 793,103. Church records gathered around 1850–1855 put the total population at 841,523, with the following composition: 51.4% Moldavians, 4.2% Russians, 21.3% Ukrainians, 10% Bulgarians, 7.2% Jews and 5.7% others. On the other hand, official data for 1855 record a total population of 980,031, excluding the population on the territory under the authority of the Special Administration of the town of Izmail. According to Ion Nistor, the population of Bessarabia in 1856 was composed of 736,000 Moldavians (74%), 119,000 Ukrainians (12%), 79,000 Jews (8%), 47,000 Bulgarians and Gagauz (5%), 24,000 Germans (2.4%), 11,000 Romani (1.1%), 6,000 Russians (0.6%), adding to a total of 990,274 inhabitants. Historian Constantin Ungureanu provides significantly different figures for the same year: 676,100 Moldavians
