The population growth of the United Kingdom has experienced significant changes over the past century. In the early 20th century, the UK saw steady growth, driven by high birth rates and declining mortality rates. However, in recent decades, the rate of population growth has slowed, influenced by lower birth rates and an aging population. Immigration has played an increasingly important role in sustaining population growth, particularly since the late 1990s. According to the Office for National Statistics, the UK's population was estimated at around 67 million in 2023, with growth rates having slowed further due to factors such as Brexit, the COVID-19 pandemic, and changing migration patterns. Looking ahead, projections suggest that the UK's population will continue to grow, but at a much slower pace, with demographic shifts posing challenges for the country's economy and public services.
