What happened
As Poland's borders shifted west, Polish and Soviet authorities agreed in September 1944 to a bilateral exchange in which ethnic Poles in the newly Soviet-annexed territories relocated to Poland and ethnic Ukrainians in Poland relocated to the Ukrainian SSR; roughly 787,000 Poles and 482,000 Ukrainians moved under this program by 1946. A substantial Ukrainian, Lemko and Boyko minority nonetheless remained in southeastern Poland, and in April–July 1947 the Polish communist government carried out Operation Vistula, forcibly dispersing roughly 140,000–150,000 of them across the newly acquired northern and western territories, partly as a security measure against the Ukrainian Insurgent Army (UPA) and partly to enforce ethnic homogenization. The dispersal deliberately broke up communities to accelerate assimilation.
Parties
Poland and the Soviet Union carried out a bilateral population exchange of Poles and Ukrainians in 1944–46; in 1947 Poland's own communist authorities then forcibly dispersed the remaining Ukrainian, Lemko and Boyko minority under Operation Vistula.
Disputed
Operation Vistula is characterized by many Ukrainian and some Polish historians as an act of ethnic cleansing and collective punishment, while it has also been presented by Polish authorities of the era as a security and pacification measure in response to UPA violence, including the killing of a senior Polish general; the Polish Senate issued a formal apology in 1990, but debate over framing and proportionality continues.
The denominator
About 1.5 million Poles were moved west from the Kresy under the 1944 republican agreements, out of a Polish population there of roughly 1.5-2 million after wartime losses. Ukrainians and Lemkos in Poland's new southeastern borderlands numbered perhaps 650,000-700,000, of whom some 480,000 were transferred east by 1946 and about 140,000 dispersed to the northern and western territories under Operation Vistula in 1947.
Two separate transfers in opposite directions are summed in the numerator, so the ratio measures total movement rather than the fate of any one community.
Where the baseline comes from
On the death toll
No comprehensive toll exists. Poland's Institute of National Remembrance records 173 death sentences passed by military tribunals during Operation Vistula in 1947, deaths from torture, typhus and suicide among the nearly 4,000 Ukrainians (including 823 women and children) interned at the Jaworzno camp, and further deaths in transit in cattle wagons during the 1944-46 Polish-Soviet exchange, which moved roughly 480,000 Ukrainians east and 780,000 Poles west. The far larger Polish-Ukrainian massacres of 1943-47 in Volhynia and Galicia are counted separately and are themselves fiercely contested between Warsaw and Kyiv.

The ~787,000 Poles moved from the Ukrainian SSR in 1944-46 in the transfers entry are part of the border-shift entry's 1.8 million Kresy Poles, which also include those moved from the Belarusian SSR (~150,000-250,000) and the Lithuanian SSR (~150,000). The official 1945-46 total from the western Soviet republics was about 1,167,000. The ~482,000-500,000 Ukrainians moved east, which appear in both entries' flows, are also shared, but they are not part of the border-shift headline figure. Operation Vistula (140,000-150,000) is not shared. 787,000 people are counted in both entries.
