The last pre-WW1 general census figures available, are from 1910 (if not including the 1911 census of school children - Sprachzählung unter den Schulkindern - which revealed a higher percent of Polish-speakers among school children than the 1910 census among the general populace). Figures (Table 1.) show that large demographic changes took place between 1819 and 1910, with the region's total population quadrupling, the percent of German-speakers increasing significantly, and that of Polish-speakers declining considerably. Also, the total land area in which Polish language was spoken, as well as the land area in which it was spoken by the majority, declined between 1790 and 1890. Polish authors before 1918 estimated the number of Poles in Prussian Upper Silesia as slightly higher than according to official German censuses. United States Immigration Commission in 1911 classified Polish-speaking Silesians as Poles.

region to Poland. The area became part of Silesian Voivodeship of the Second Polish Republic.

. The expulsions of German-speakers did not totally eliminate the presence of a population that considered itself German. In contrast to the situation in Lower Silesia, where almost the totality of the pre-war population that was expelled was exclusively German-speaking, the pre-war population of Upper Silesia was in considerable number Roman Catholic mixed bilingual that spoke both German and Polish dialects, and their Polish linguistic skills were considered solid enough for them to be kept in the area. The area formally became part of the Republic of Poland by virtue of the German-Polish border treaty of November 14, 1990. With the fall of communism and Poland's joining the European Union, there were enough of these remaining in Upper Silesia to allow for the recognition of the German minority in Poland by the Polish government.
