Ukraine's Jewish population will only decline from here

With religious aspects of Judaism strongly suppressed in the Soviet Union and Yiddish culture all but destroyed after the Second World War, Soviet Jews were left with an extremely limited knowledge of Jewish religion or culture, able only to be identified as Jews by nationality or to affirm their Jewishness on the grounds of being part of a minority group with common ancestry.

Intermarriage and assimilation became increasingly common, making the boundaries between who is and who is not Jewish increasingly difficult to draw.

In part because of this, Jewish demographers measure the size of Jewish populations today using four different inclusion criteria.

The most common one is what is known as the ‘core’ Jewish population: it includes anyone who, when asked in a survey or census ‘what is your religion?’ or ‘what is your ethnicity?’, responds by self-identifying as Jewish. In Ukraine today, the number of Jews is about 45,000 according to this criterion.

The second definition used enumerates the ‘population with Jewish parents.’ This includes most of those in the core Jewish population, but adds others who do not consider themselves to be Jewish yet have at least one Jewish parent.

Given that Jewishness is seen more as a matter of ancestry than religion in Ukraine, this is an important approach there. Demographers estimate the population based on this criterion at 90,000.

Then there is what is known as the ‘enlarged Jewish population’ – including anyone who self-identifies as Jewish, plus anyone else living within their household, such as their spouse or children, irrespective of whether they are Jewish or not.

Again, this is an important consideration in places such as Ukraine: when Jewish organisations provide care or support for Jews there, it would be wrong to limit that only to the Jewish partner in a mixed couple – imagine delivering a hot meal to an elderly impoverished Jewish man, but not to his equally impoverished and elderly non-Jewish wife. Using this criterion, the population is estimated at 140,000.

Finally, there is the ‘Law of Return population’ – i.e. the number of people eligible for Israeli citizenship under the terms of Israel’s Law of Return.

This applies to anyone who is the descendant of at least one Jewish grandparent, irrespective of whether or not they personally identify as Jewish, and it extends to their immediate family members living within their household, again, irrespective of whether or not they see themselves as Jewish. Using this as our criterion, the population reaches about 200,000.

So, as you can see, the 400,000 claim is way off. But then again, it might just be excusable. Why? Because just over thirty years ago, when the Berlin Wall came down, the core Jewish population of Ukraine numbered 487,000.

It has declined year-on-year since then, very rapidly during the 1990s due largely to out-migration, slowing somewhat during the 2000s, before speeding up again following the 2014 unrest. In fact, the Jewish population of Ukraine is estimated to have declined by 91% over the past three decades. And with everything going on now, further decline is inevitable
