Religion
Given below is an overview of the religion-wise break-up of the population across the subdivisions of North 24 Parganas district, as per 2011 census:

North 24 Parganas district with 24.22% Muslims (in 2001) has been identified as a minority concentrated district by the Ministry of Minority Affairs, Government of India. A baseline survey on religious minority population has been carried out under the aegis of Indian Council of Social Science Research and funded by the Ministry of Minority Affairs. For information on the survey see North 24 Parganas: minority concentrated district. Population movement
North 24 Parganas district is densely populated, mainly because of the influx of refugees from East Pakistan (later Bangladesh). With a density of population of 2,182 per km2 in 1971, it was 3rd in terms of density per km2 in West Bengal after Kolkata and Howrah, and 20th in India. According to the District Human Development Report: North 24 Parganas, “High density is also explained partly by the rapid growth of urbanization in the district. In 1991, the percentage of urban population in the district has been 51.23.”

The census figures show the number of refugees from East Pakistan in 1971 was nearly 6 million (60 lakhs) and in 1981, the number was assessed at 8 million (80 lakhs). A district-wise break-up in 1971, shows the main thrust of the refugee influx was on 24-Parganas (22.3% of the total refugees), Nadia (20.3%), Bankura (19.1%) and Kolkata (12.9%). The North 24 Paraganas district has a 352 km long international border with Bangladesh, out of which 160 km is land border and 192 km is riverine border. Only a small portion of the border has been fenced and it is popularly referred to as a porous border. There are reports of Bangladeshi infiltrators. The CD Block pages carry Decadal Population Growth information. An estimate made in 2000 places the total number of illegal Bangladeshi immigrants in India at 1.5 crore, with around 3 lakh entering every year. The thumb rule for such illegal immigrants is that for each illegal person caught four get through. While many immigrants have settled in the border areas, some have moved on, even to far way places such as Mumbai and Delhi. The border is guarded by the Border Security Force. During the UPA government, Sriprakash Jaiswal, Union Minister of State for Home Affairs, had made a statement in Parliament on 14 July 2004, that there were 12 million illegal Bangladeshi infiltrators living in India, and West Bengal topped the list with 5.7 million Bangladeshis. More recently, Kiren Rijiju, Minister of State for Home Affairs in the NDA government has put the figure at around 20 million. Administrative units
