Why did the Cochin Jewish community decline after the mid-20th century?

The decline of the Cochin Jewish community in Keralam after the mid-20th century was primarily driven by large-scale emigration, particularly to Israel.12

During the 1950s, the Malabari group—which comprised approximately 2,400 individuals—moved to Israel almost in its entirety. Many members of the Paradesi community also eventually emigrated to Israel, where they continued to maintain and pass on their traditions. This mass departure significantly reduced the population, which had once numbered in the thousands, leaving only about 50 Cochin Jews remaining on the Malabar Coast by the early 21st century. Consequently, while the region historically supported eight active synagogues, only the Paradesi Synagogue in Kochi remained active by that time.1
