The population of the United Kingdom in 2024 was estimated to be approximately 69.3 million, with over 9.6 million people living in South East England. London had the next highest population, at almost 9.1 million people, followed by the North West England at 7.7 million. With the UK's population generally concentrated in England, most English regions have larger populations than the constituent countries of Scotland, Wales, and Northern Ireland, which had populations of 5.5 million, 3.2 million, and 1.9 million respectively. English counties and cities The United Kingdom is a patchwork of various regional units, within England the largest of these are the regions shown here, which show how London, along with the rest of South East England had around 18 million people living there in this year. The next significant regional units in England are the 47 metropolitan and ceremonial counties. After London, the metropolitan counties of the West Midlands, Greater Manchester, and West Yorkshire were the biggest of these counties, due to covering the large urban areas of Birmingham, Manchester, and Leeds respectively. Regional divisions in Scotland, Wales and Northern Ireland The smaller countries that comprise the United Kingdom each have different local subdivisions. Within Scotland these are called council areas, whereas in Wales the main regional units are called unitary authorities. Scotland's largest Council Area by population is that of Glasgow City at over 650,000, while in Wales, it was the Cardiff Unitary Authority at around 384,000. Northern Ireland, on the other hand, has eleven local government districts, the largest of which is Belfast with a population of approxiamtely 352,000.

According to the 2021 Census, London was the most ethnically diverse region in England and Wales – 63.2% of residents identified with an ethnic minority group.

In 2024/25, there were 104 homicide offences recorded in London, the most of any region of the United Kingdom during that time period. North West England, which includes the large cities of Manchester and Liverpool, had 69 homicides and had the second-highest number of homicides. In the same reporting period, the constituent countries of Wales and Northern Ireland reported the fewest homicides, at 23, and 13 respectively. Homicides in the UK falling despite recent uptick Since 2002/03, all three jurisdictions of the UK; England and Wales, Scotland, and Northern Ireland, have seen their homicide rates fall, with Scotland seeing the steepest decline. The most significant decline in homicides in this period occurred between 2002/03 and 2014/15, which saw the annual number of homicides in England and Wales half from over 1,000 to around 500. This trend was suddenly reversed from 2015/16 onwards, with homicides rising to around 700 per year between 2016/17 and 2019/20. While homicides fell back to 535 in 2024/25, it remains to be seen if this pattern will continue. Knives used in almost half of all murders In 2024/25 a knife or other sharp instruments were used in approximately 46 percent of all murders in England and Wales, making this, by far, the most common method of killing in that reporting year. The overall number of knife homicides reached 262 in 2023/24, compared with 243 in the previous year. Firearm homicides were much rarer than knife homicides, with only 22 taking place in the same reporting year, and homicides caused by shooting only accounting for 3.9 percent of homicides overall.

There were 20,944 incidences of racist hate crime reported by the London Metropolitan Police in the 2023/24 reporting year, by far the most of any police force area in England and Wales. In the same time period, there were 7,466 racist incidents reported in the West Midlands.

In 2023, London had a gross domestic product of over 569 billion British pounds, by far the most of any region of the United Kingdom. The region of South East England which surrounds London had the second-highest GDP in this year, at over 360 billion pounds. North West England, which includes the major cities of Manchester and Liverpool, had the third-largest GDP among UK regions, at almost 250 billion pounds. Levelling Up the UK London’s economic dominance of the UK can clearly be seen when compared to the other regions of the country. In terms of GDP per capita, the gap between London and the rest of the country is striking, standing at over 63,600 pounds per person in the UK capital, compared with just over 37,100 pounds in the rest of the country. To address the economic imbalance, successive UK governments have tried to implement "levelling-up policies", which aim to boost investment and productivity in neglected areas of the country. The success of these programs going forward may depend on their scale, as it will likely take high levels of investment to reverse economic neglect regions have faced in the recent past. Overall UK GDP The gross domestic product for the whole of the United Kingdom amounted to 2.56 trillion British pounds in 2024. During this year, GDP grew by 0.9 percent, following a growth rate of 0.4 percent in 2023. Due to the overall population of the UK growing faster than the economy, however, GDP per capita in the UK fell in both 2023 and 2024. Nevertheless, the UK remains one of the world’s biggest economies, with just five countries (the United States, China, Japan, Germany, and India) having larger economies. It is it likely that several other countries will overtake the UK economy in the coming years, with Indonesia, Brazil, Russia, and Mexico all expected to have larger economies than Britain by 2050.

With approximately 122.1 crimes per 1,000 population, Cleveland, in North East England, had the highest crime rate of all the police force areas in England and Wales in 2024/25. High crime rates are evident in other areas of northern England, such as West Yorkshire and Greater Manchester at 114.5 and 108.2, respectively. In the UK capital, London, the crime rate was 105.5 per 1,000 people. The lowest crime rate in England was in the relatively rural areas of Wiltshire in South West England, as well as North Yorkshire. Overall crime in England and Wales The number of crimes in England and Wales reached approximately 6.74 million in 2022/23, falling slightly to 6.66 million in 2023/24, and 6.59 million in 2024/25. Overall crime has been rising steadily across England and Wales for almost a decade, even when adjusted for population rises. In 2022/23, for example, the crime rate in England and Wales was 93.6, the highest since 2006/07. When compared with the rest of the United Kingdom, England and Wales is something of an outlier, as crime rates for Scotland and Northern Ireland have not followed the same trajectory of rising crime. Additionally, there has been a sharp increase in violent crimes and sexual offences since the mid-2010s in England and Wales. While theft offences have generally been falling, the number of shoplifting offences reached a peak of 530,640 in 2024/25. Troubled justice system under pressure Alongside rising crime figures, many indicators also signal that the justice system is getting pushed to breaking point. The percentage of crimes that are solved in England and Wales was just 5.7 percent in 2023, with sexual offences having a clearance rate of just 3.6 percent. Crimes are also taking far longer than usual to pass through the justice system. In 2022, it took an average of 407 days for a crown court case to reach a conclusion from the time of the offence, compared with 233 days in 2018. This is most likely related to the large backlog of cases in crown courts, which reached over 67,750 in 2023. Furthermore, prisons in England and Wales are dangerously overcrowded, with the government even releasing some prisoners early to address the issue.
