The concept of demographic threat (or demographic bomb) is a term used in political conversation to refer to population increases from within a minority ethnic group in a given country that are perceived as threatening to alter the ethnic identity of that country.
Thousands of Bahraini Shia Muslims protested in March 2011 against the Bahraini government's naturalisation policy of granting citizenships to Sunni Muslims from other countries serving in the military of Bahrain.
There was a demographic competition during 19th and 20th centuries, between French-speaking Catholics minority and English-speaking Protestants majority.
In Estonia, one of the causes of the Singing Revolution was the concern over the demographic threat to the national identity posed by the influx of individuals from foreign ethnic groups to work on such large Soviet development projects as phosphate mining.
Alleged mass immigration from Arab and Muslim countries, and the high fertility rate among these immigrants are described by many conservatives as posing a demographic threat to Europe, especially France. Some of those conservatives have claim that today about a third of newborn in France have Muslim parents.
In Kosovo, Albanian settlement led to Albanian majority during 20th century, complex demographic tensions, and eventually a Republic of Kosovo's declaration of independence in early 21st century.
Many Hindu Indians see Muslims as a "demographic threat" because of their large population growth due to high fertility rates and because of the high rate of illegal immigration from Bangladesh.
In the 1950s, Shoham Melamad found that the high fertility rate of Arabs was viewed as a demographic threat to the Jewish nation. Rabbi Menachem M. Schneerson, however, stated that Arabs in Israel should be treated equally to any other Israeli citizens and be allowed to have children just like any other citizen. A 1967 Maariv editorial suggested that Jews should be encouraged to have large families, while Palestinians in the West Bank, Gaza Srip and in Israel should be encouraged to adopt birth control measures. Schnitzer also advocated for the adoption of an open policy encouraging Arabs to emigrate from Israel. In 2003, Benjamin Netanyahu opined that if the percentage of Arab citizens of Israel rises above its current level of about 20 percent, Israel would not be able to retain a Jewish demographic majority, the basis of Israel's self-definition as a "Jewish democratic state". Netanyahu's comments were criticized as racist by Arab Knesset members and the Association for Civil Rights in Israel. In May 2009, Michael Oren, the current Israeli Ambassador to the USA, wrote an article in Commentary Magazine in which he discussed the "Arab Demographic Threat" as one of "Seven Existential Threats" facing Israel. Shimon Peres and Benjamin Netanyahu both warned that Bedouin population growth in the Negev was a "demographic" or "palpable" threat to a Jewish majority.
Russia fears the "demographic threat" posed by the potential for "large-scale Chinese immigration" to its thinly populated far east. Illegal immigration of Chinese nationals is a special concern.
Some in the United States have expressed concern about the "demographic threat" posed by millions of illegal immigrants from Mexico and Latin America, and their descendants. George Friedman, the head of Stratfor, predicts that Mexicans will be a majority in the Southwestern United States by the end of the 21st century.
