Question: How many Jews live in the country where Léon Diguet was educated?

camille pelletan was educated in paris, passed as licentiate in laws, and studied at the "école nationale des chartes" where he was qualified as an "archiviste paléographe". at the age of twenty he became an active journalist, and a bitter critic of the imperial government. after the war of 1870-71 he took a leading place among the radicals, as an opponent of the "opportunist republicans" who continued the policy of léon gambetta. <SEP> prior to 1948, approximately 800,000 jews were living in lands which now make up the arab world (excluding israel). of these, just under two-thirds lived in the french-controlled maghreb region, 15–20% in the kingdom of iraq, approximately 10% in the kingdom of egypt and approximately 7% in the kingdom of yemen. a further 200,000 lived in pahlavi iran and the republic of turkey. today, around 26,000 jews live in arab countries and around 30,000 in iran and turkey. a small-scale exodus had begun in many countries in the early decades of the 20th century, although the only substantial aliyah came from yemen and syria. the exodus from arab and muslim countries took place primarily from 1948. the first large-scale exoduses took place in the late 1940s and early 1950s, primarily in iraq, yemen and libya, with up to 90% of these communities leaving within a few years. the peak of the exodus from egypt occurred in 1956. the exodus in the maghreb countries peaked in the 1960s. lebanon was the only arab country to see a temporary increase in its jewish population during this period, due to an influx of refugees from other arab countries, although by the mid-1970s the jewish community of lebanon had also dwindled. in the aftermath of the exodus wave from arab states, an additional migration of iranian jews peaked in the 1980s when around 80% of iranian jews left the country. [citation needed] <SEP> Western Europe's largest Jewish community, and the third-largest Jewish community in the world, can be found in France, home to between 483,000 and 500,000 Jews, the majority of whom are immigrants or refugees from North African Arab countries such as Algeria, Morocco, and Tunisia (or their descendants). The United Kingdom has a Jewish community of 292,000. In Eastern Europe, there are anywhere from 350,000 to one million Jews living in the former Soviet Union, but exact figures are difficult to establish. In Germany, the 102,000 Jews registered with the Jewish community are a slowly declining population, despite the immigration of tens of thousands of Jews from the former Soviet Union since the fall of the Berlin Wall. Thousands of Israelis also live in Germany, either permanently or temporarily, for economic reasons. <SEP> Various short-lived organizations of anthropologists had already been formed. The Société Ethnologique de Paris, the first to use Ethnology, was formed in 1839. Its members were primarily anti-slavery activists. When slavery was abolished in France in 1848 the Société was abandoned. Sporadic use of the term for some of the subject matter occurred subsequently, such as the use by Étienne Serres in 1838 to describe the natural history, or paleontology, of man, based on comparative anatomy, and the creation of a chair in anthropology and ethnography in 1850 at the National Museum of Natural History (France) by Jean Louis Armand de Quatrefages de Bréau. <SEP> He studied science at the Muséum national d'histoire naturelle in Paris, where he was influenced by scientists that included biologist Jean Louis Armand de Quatrefages de Bréau, zoologist Alphonse Milne-Edwards, and anthropologist Ernest Hamy. During that period, he explored the peninsula's interior, collecting natural history specimens for the National Museum of Natural History in Paris. From 1889 to 1892, he was employed as a chemical engineer at the French-owned El Boleo mining installation in Santa Rosalia, Baja California Sur. Afterwards, from 1893 to 1914, he made six more trips to Mexico as an explorer and collector:
