Judaism/Jewish Population
According to Wikipedia "As of 2020, the world's "core" Jewish population (those identifying as Jews above all else) was estimated at 14.8 million, 0.19% of the 7.95 billion worldwide population. This number rises to 18 million with the addition of the "connected" Jewish population, including those who say they are partly Jewish or that have Jewish backgrounds from at least one Jewish parent, and rises again to 21 million with the addition of the "enlarged" Jewish population, including those who say they have Jewish backgrounds but no Jewish parents and all non-Jewish household members who live with Jews. Counting all those who are eligible for Israeli citizenship under Israel's Law of Return, in addition to Israeli Jews, raised the total to 23.8 million."
