Religion in Nigeria: Nigeria, the most populous African country (with a population of over 182 million in 2015), is nearly equally divided between Christianity and Islam, though the exact ratio is uncertain.

The 1963 Nigerian census found that 36% of the population was Christian, 38% Muslim, and 26% other; the 2008 MEASURE Demographic and Health Survey (DHS) found 53% Muslim, 45% Christian, and 2% other; the 2008 Afrobarometer poll found 50% Christian, 49% Muslim, and 1% other; Pew's own survey found 52% Muslim, 46% Christian, and 1% other.

History of the Jews in Malaysia: Malaysian Jews are Jews living in Malaysia, or those originally from the country.

Indications of the growing racial and religious hostility in the nation has caused many Malaysian Jews to leave or flee the country.
