Question: Which location has a larger population, the Jiangdu District or Hailun?
Context: Walpole is a small census-designated place (CDP) located within the much larger town (21 square miles in size) of Walpole in Norfolk County, Massachusetts, United States.  Walpole Town as it is called by the US Census Bureau, also includes a much larger population (24,070 in 2010).  The population of the Census Designated Place was 5,918 at the 2010 census. Riverview is a Canadian town in Albert County, New Brunswick, Canada.  Riverview is located on the south side of the Petitcodiac River, across from the larger cities of Moncton and Dieppe.

With a population of 19,667, Riverview is the fifth largest municipality in New Brunswick, having a larger population than the cities of Edmundston, Bathurst, Campbellton, and Miramichi, despite its designation of "town". Hailun () is a city in west-central Heilongjiang province, People's Republic of China.  Administratively, it is a county-level city of Suihua City.

Statistical inference is the process of deducing properties of an underlying probability distribution by analysis of data.  Inferential statistical analysis infers properties about a population: this includes testing hypotheses and deriving estimates.  The population is assumed to be larger than the observed data set; in other words, the observed data is assumed to be sampled from a larger population. The Squamish-Lillooet Regional District is a quasi-municipal administrative area in British Columbia, Canada.  It stretches from Britannia Beach in the south to Pavilion in the north.  Lillooet, Pemberton, Whistler and Squamish are the four municipalities in the regional district.  Its administrative offices are in the Village of Pemberton, although the district municipalities of Squamish, Whistler, and Lillooet are all larger population centres.  The district covers 16,353.68 km² (6,314.19 sq mi) of land area. In population genetics, the founder effect is the loss of genetic variation that occurs when a new population is established by a very small number of individuals from a larger population.  It was first fully outlined by Ernst Mayr in 1942, using existing theoretical work by those such as Sewall Wright.  As a result of the loss of genetic variation, the new population may be distinctively different, both genotypically and phenotypically, from the parent population from which it is derived.  In extreme cases, the founder effect is thought to lead to the speciation and subsequent evolution of new species. Islam is historically divided into two major sects, Sunni and Shia Islam, each with its own sub-sects.  Large numbers of Shia Arab Muslims live in some Arab countries including Lebanon, Yemen, Iraq, Saudi Arabia, Kuwait, Oman, the UAE, and Qatar.  Shia Muslims are a numerical majority in Iraq and Bahrain.  Approximately half of the population in Yemen are Shia Muslims.  Exactly half of Muslims in Lebanon are Shia Muslims.  There is also a very large population of Shia Muslims living in the Arab Persian Gulf countries especially in Saudi Arabia.  Approximately the whole population of East Saudi Arabia, the Eastern Province are Shia Muslims.  Although government statistics claim that roughly only 20-40% of the Muslim population are Shia Muslims, there has been dispute to the authenticity of this figure and recent reports and investigations indicate that there is in fact a much larger population of Shia Muslims present, with estimate figures over 45% or even making the majority of Muslim population.  Saudi Arabia follows a strict recently established sect of Islam, Wahhabism, there is little freedom of religion between the different sects even whilst all of the population are Muslims.  Smaller Shia groups are present in Egypt and Jordan.  Despite the heavy presence of Shia Muslims in some Arab countries, particularly among the population of the Persian Gulf Arab countries, they have been treated poorly throughout history.  Additionally, in recent times, Shia Muslims along with Kurds have faced genocide by the pan-Arabist regime of Saddam Hussein.  For both historical and political reasons, the Shia have fared rather poorly in much of the Arab world, and the topic of Shi‘ism and Shia groups is one of the most sensitive issues for the Sunni elite.  This article discusses both the history of Shī‘a Islam in the Arab world from the dawn of Islam and their current situation in the Arabic-speaking world.
