Between 1500 and 1800, London grew to be the largest city in Western Europe, with its population growing almost 22 times larger in this period. London would eventually overtake Constantinople as Europe's largest in the 1700s, before becoming the largest city in the world (ahead of Beijing) in the early-1800s.

The most populous cities in this period were the capitals of European empires, with Paris, Amsterdam, and Vienna growing to become the largest cities, alongside the likes of Lisbon and Madrid in Iberia, and Naples or Venice in Italy. Many of northwestern Europe's largest cities in 1500 would eventually be overtaken by others not shown here, such as the port cities of Hamburg, Marseilles or Rotterdam, or more industrial cities such as Berlin, Birmingham, and Munich.

Chart and table of population level and growth rate for the London, Canada metro area from 1950 to 2025.

The population of London was approximately 8.9 million in 2023, an increase of over two million people when compared with the early 1980s. Throughout the 1980s, the population of the United Kingdom's capital grew at a relatively slow rate, before accelerating to a much faster rate in the 1990s. London is by far the largest city / urban agglomeration in the United Kingdom, more than three times larger than the next largest cities of Manchester and Birmingham. London’s forecasted population is expected to continue growing at much the same pace it has been growing since the mid-1990s and reach almost 9.8 million by 2042. London boroughs As of 2022, the London borough with the highest population was Croydon, at approximately 392,224, followed by Barnet at 389,101. Overall, London is divided into 33 different boroughs, with London's historic center, the City of London having by far the smallest population, at just 10,847. Residents of the City of London, however, have the highest average median weekly earnings among all of London's boroughs, at 1,138 pounds per week, compared with just 588 pounds per week in Redbridge, the lowest average weekly earnings among London boroughs. While the overall unemployment rate for London was 4.3 percent in early 2023, this ranged from 6.8 percent in Brent, to just 2.3 percent in Kingston upon Thames.
Economic imbalance Aside from being the UK's largest city in terms of population, London is also undoubtedly the UK's cultural, political and economic center. As of 2021, the GDP of Greater London was approximately 496.4 billion British pounds, just over 23 percent of the UK's overall GDP. In the same year, GDP per person in London was 56,431 pounds compared with the UK average of 31,947 pounds. Additionally, productivity in London is far higher than the UK average. As measured by output per hour worked, London was 33.2 percent more productive than the rest of the UK.

In 2023, the population of the United Kingdom reached 68.3 million, compared with 67.6 million in 2022. The UK population has more than doubled since 1871 when just under 31.5 million lived in the UK and has grown by around 8.2 million since the start of the twenty-first century. For most of the twentieth century, the UK population steadily increased, with two noticeable drops in population occurring during World War One (1914-1918) and in World War Two (1939-1945). Demographic trends in postwar Britain After World War Two, Britain and many other countries in the Western world experienced a 'baby boom,' with a postwar peak of 1.02 million live births in 1947. Although the number of births fell between 1948 and 1955, they increased again between the mid-1950s and mid-1960s, with more than one million people born in 1964. Since 1964, however, the UK birth rate has fallen from 18.8 births per 1,000 people to a low of just 10.2 in 2020. As a result, the UK population has gotten significantly older, with the country's median age increasing from 37.9 years in 2001 to 40.7 years in 2022. What are the most populated areas of the UK? The vast majority of people in the UK live in England, which had a population of 57.7 million people in 2023. By comparison, Scotland, Wales, and Northern Ireland had populations of 5.44 million, 3.13 million, and 1.9 million, respectively. Within England, South East England had the largest population, at over 9.38 million, followed by the UK's vast capital city of London, at 8.8 million. London is far larger than any other UK city in terms of urban agglomeration, with just four other cities; Manchester, Birmingham, Leeds, and Glasgow, boasting populations that exceed one million people.

Figure for Year-1939 is a mid-year estimate for the year 1939. Figure for Year-2001 onwards is the number of residents because the number of persons present is not available from 2001. Note that totals for Greater London may not match due to rounding errors. Figures are estimates to the nearest thousand.

By 2043 it is expected that there will be approximately 4.99 million men and 4.82 million women living in London, compared with 4.66 million men and almost 4.6 million women in 2025. London’s population since 1981 Between 1981 and 1988, the population of London declined from 6.8 million, to 6.73 million. This period of gradual population decline was, however, followed by a sustained era of population growth, with London's population reaching a peak of 8.9 million in 2019. In the years since that peak, the population of the capital has declined slightly and, as of 2022, was 8.86 million. London's boroughs London is currently split up into 32 boroughs, as well as the historic center of the city, the City of London. The City of London had a population of just 10,847 people in 2022, compared with 392,224 in Croydon, the London Borough with the highest population that year. London's historic center also had the highest average weekly salary in the city, at 1,138 pounds, compared with 588 pounds in the Borough of Redbridge.

As of 2020, 131 thousand Italians were living in London. From 2015 to 2017, the number of Italian citizens who lived in the English Capital increased steadily. However, the Italian population living in London fell between 2018 and 2019. Nonetheless, the United Kingdom is the most popular destination country among Italian emigrants. During 2019, about 19 percent of all Italians who moved abroad notably chose the United Kingdom.

Student migration

The United Kingdom is a very common destination among young Italians in particular. In addition, a large percentage of emigrants who moved to the United Kingdom achieved a higher education. Specifically, 31 percent of Italians who live in the United Kingdom hold a university degree. However, the countries with most Italian emigrants holding a university degree are Brazil, Ireland, and the United States.

Historical migration of Italians

Currently, Argentina has the largest Italian population living abroad. Historically, Argentina was one of the most important destinations of Italian emigrants, especially during the nineteenth and twentieth centuries. Currently, Argentina ranks only tenth among the main destination countries of Italians. The most common destinations are, together with the United Kingdom, Germany and France.

Although the Black Death peaked in Europe between 1348 and 1351, plague was almost always present in Britain for the next four centuries. In most years, plague was a dormant threat that affected very few people, and diseases such as smallpox and influenza were much more widespread; however, bubonic plague was prone to outbreaks that could decimate populations in a few short years. In London, plague outbreaks occurred every few decades, usually with death tolls in the tens of thousands. The duration and severity of these epidemics varied, sometimes having high death tolls but subsiding quickly, while others had relatively lower death tolls but could last for a number of years. As London's population and density also grew drastically during this period, plague affected the city differently in the sixteenth and seventeenth centuries. Great Plague of London The final major plague epidemic observed in Britain took place in 1665 and 1666. It became known as the "Great Plague" as it was the last of its kind in Britain, and its death toll eclipsed all other epidemics in the preceding century (although it was much smaller than that of the Black Death). The plague lasted for eighteen months, and had a reported death toll of more than 70,000 in this time; although modern historians estimate that the actual death toll exceeded 100,000. At its peak in September 1665, it is reported that there were more than 7,000 deaths per week, although this may have also been much higher due to the limited records kept at the time. Another reason for the lack of accurate records relating to this epidemic is because of the Great Fire of London in 1666. The fire started on September 02. 1666, and destroyed almost all of the city within the walls, leaving thousands homeless. Historians continue to debate the fire's significance, some citing that it destroyed the unsanitary dwellings where infected rats lived and drove them from the city, while others claim that the timings were purely coincidental and that the epidemic had already begun to subside in February.

This collection provides a complete list of convict names and sufficient biographical data to enable unambiguous identification of convicts who were disembarked from convict ship "London (2)" at Van Diemen's Land on 1851-03-19

This includes, where known, an estimation of the year of birth, place of birth, where and when convicted, the sentence, the date of arrival in the colony and the convict's age on arrival. The brief convict biographical data provided in this collection serves as an index into the far more extensive set of life course events which are recorded in the prosopgraphy database built by the Founders and Survivors project.

Basic details for this ship: * ship name (as known in VDL records): London (2) * sailed date : 1850-12-20 from Dublin * arrival date : 1851-03-19 * population (per Bateson's The Convict Ships): Embarked:288 Men ; Deaths:3 Men ; Landed:285(VDL) Men

Data for convicts listed in this collection comes from the source which has been determined by Founders and Survivors to form the "base population" for this ship. Further information as to the methodology and the linkage of multiple sources is detailed in the narrative format of the collection. The matching and linkage of additional sources about Tasmanian convict's is the subject of ongoing research. This collection may be repuplished regularly, and in additional formats and with specific user interfaces, to enable public participation in the quality of convict matching and linkage -- see for example the EXPERIMENTAL linkage.htm format for this collection. Linkage for ships arriving at Norfolk Island and Port Philip is incomplete.

This ship's prosopography index is published in a directory named "370.18" (the ship's project id). Three three different file formats provided: -- (default; suitable for web browsing) HTML: world wide web hypertext markup language format which provides a "narrative" view of the collection (index.htm); and -- (structured prosopgraphy: persons and events) XML / TEIp5 : Text Encoding Initiative (version p5) XML format which provides the underlying XML database for this collection (index.xml); and -- Not yet available simple list of convict names in a flat file, tab delimited, suitable for Excel, Stata, SPSS or database usage (index.tab).

It is only in the past two centuries where demographics and the development of human populations has emerged as a subject in its own right, as industrialization and improvements in medicine gave way to exponential growth of the world's population. There are very few known demographic studies conducted before the 1800s, which means that modern scholars have had to use a variety of documents from centuries gone by, along with archeological and anthropological studies, to try and gain a better understanding of the world's demographic development. Genealogical records One such method is the study of genealogical records from the past; luckily, there are many genealogies relating to European families that date back as far as medieval times. Unfortunately, however, all of these studies relate to families in the upper and elite classes; this is not entirely representative of the overall population as these families had a much higher standard of living and were less susceptible to famine or malnutrition than the average person (although elites were more likely to die during times of war). Nonetheless, there is much to be learned from this data. Impact of the Black Death In the centuries between 1200 and 1745, English male aristocrats who made it to their 21st birthday were generally expected to live to an age between 62 and 72 years old. The only century where life expectancy among this group was much lower was in the 1300s, where the Black Death caused life expectancy among adult English noblemen to drop to just 45 years. Experts assume that the pre-plague population of England was somewhere between four and seven million people in the thirteenth century, and just two million in the fourteenth century, meaning that Britain lost at least half of its population due to the plague. Although the plague only peaked in England for approximately eighteen months, between 1348 and 1350, it devastated the entire population, and further outbreaks in the following decades caused life expectancy in the decade to drop further. The bubonic plague did return to England sporadically until the mid-seventeenth century, although life expectancy among English male aristocrats rose again in the centuries following the worst outbreak, and even peaked at more than 71 years in the first half of the sixteenth century.

This project examines the crucial role of family and household in the social and economic transformations that took place in London in the sixteenth and seventeenth centuries. Population growth, immigration, urbanisation, and commercialisation produced new patterns of sociability, gender relations, employment, and domestic lifestyle. The family was central to all these developments, but has been little studied in detail. The project will reconstruct and analyse the dense matrix of families, households, properties, and buildings in sample areas of the capital, and trace their evolution over time, gaining new insights into social structures and the agents and circumstances of change.
Main Topics:

The digital resource comprises a series of datasets which contain information about individuals, households and properties transcribed and extracted from a wide range of sources from the period 1540-1710 (a complete list of sources is included in the documentation for the database). The project database contains information on over 60,000 individuals, as well as over 24,000 records of 'listing type' information for five parishes at the eastern end of Cheapside, and 5000 such records for Tower Hill precinct in the parish of St Botolph Aldgate. The information provided in these records comprises names, titles, places of residence (by ward and/or parish and/or street), occupations, and where appropriate an assessment of sums owed according to the function of each particular list.

The datasets also include family reconstitutions for the five Cheapside parishes and Clerkenwell, and derived from parish register entries (there was almost complete and continuous register coverage). In all, the data covers 22,324 instances of people experiencing a baptism, marriage or burial in Cheapside, and 19,095 instances of persons related to them; 140,713 people experiencing a vital event in Clerkenwell and 95,927 'related' people. These data have been used for the reconstitution of 3,809 biological/nuclear families containing 9,027 unique children in Cheapside and 26,324 reconstituted families containing 44,052 unique children in Clerkenwell.

In addition to the project database and the family reconstitution data, a number of sources have been transcribed in a structured format which allows for the viewing of the individual sources used in the database without the need for viewing any related data from other sources.

In 1800, the population of the area of modern-day Bangladesh was estimated to be just over 19 million, a figure which would rise steadily throughout the 19th century, reaching over 26 million by 1900. At the time, Bangladesh was the eastern part of the Bengal region in the British Raj, and had the most-concentrated Muslim population in the subcontinent's east. At the turn of the 20th century, the British colonial administration believed that east Bengal was economically lagging behind the west, and Bengal was partitioned in 1905 as a means of improving the region's development. East Bengal then became the only Muslim-majority state in the eastern Raj, which led to socioeconomic tensions between the Hindu upper classes and the general population. Bengal Famine During the Second World War, over 2.5 million men from across the British Raj enlisted in the British Army and their involvement was fundamental to the war effort. The war, however, had devastating consequences for the Bengal region, as the famine of 1943-1944 resulted in the deaths of up to three million people (with over two thirds thought to have been in the east) due to starvation and malnutrition-related disease. As the population boomed in the 1930s, East Bengal's mismanaged and underdeveloped agricultural sector could not sustain this growth; by 1942, food shortages spread across the region, millions began migrating in search of food and work, and colonial mismanagement exacerbated this further. On the brink of famine in early-1943, authorities in India called for aid and permission to redirect their own resources from the war effort to combat the famine, however these were mostly rejected by authorities in London. While the exact extent of each of these factors on causing the famine remains a topic of debate, the general consensus is that the British War Cabinet's refusal to send food or aid was the most decisive. Food shortages did not dissipate until late 1943, however famine deaths persisted for another year. Partition to independence Following the war, the movement for Indian independence reached its final stages as the process of British decolonization began. Unrest between the Raj's Muslim and Hindu populations led to the creation of two separate states in1947; the Muslim-majority regions became East Pakistan (now Bangladesh) and West Pakistan (now Pakistan), separated by the Hindu-majority India. Although East Pakistan's population was larger, power lay with the military in the west, and authorities grew increasingly suppressive and neglectful of the eastern province in the following years. This reached a tipping point when authorities failed to respond adequately to the Bhola cyclone in 1970, which claimed over half a million lives in the Bengal region, and again when they failed to respect the results of the 1970 election, in which the Bengal party Awami League won the majority of seats. Bangladeshi independence was claimed the following March, leading to a brutal war between East and West Pakistan that claimed between 1.5 and three million deaths in just nine months. The war also saw over half of the country displaced, widespread atrocities, and the systematic rape of hundreds of thousands of women. As the war spilled over into India, their forces joined on the side of Bangladesh, and Pakistan was defeated two weeks later. An additional famine in 1974 claimed the lives of several hundred thousand people, meaning that the early 1970s was one of the most devastating periods in the country's history. Independent Bangladesh In the first decades of independence, Bangladesh's political hierarchy was particularly unstable and two of its presidents were assassinated in military coups. Since transitioning to parliamentary democracy in the 1990s, things have become comparatively stable, although political turmoil, violence, and corruption are persistent challenges. As Bangladesh continues to modernize and industrialize, living standards have increased and individual wealth has risen. Service industries have emerged to facilitate the demands of Bangladesh's developing economy, while manufacturing industries, particularly textiles, remain strong. Declining fertility rates have seen natural population growth fall in recent years, although the influx of Myanmar's Rohingya population due to the displacement crisis has seen upwards of one million refugees arrive in the country since 2017. In 2020, it is estimated that Bangladesh has a population of approximately 165 million people.
