Swansea History

The history of Swansea dates back thousands of years, with human remains found in the area that dated all the way back to 22,000 BC. Swansea was well-known during the Industrial Revolution because of its role in the tinplate industry. Approximately 90% of the world’s copper was smelted in this city, leading to the nickname Copperopolis. Because of its role in industrialization, Swansea experienced a period of urban growth and transportation systems were introduced. In fact, Swansea was home to The Mumbles Railway, a railway that was put into use in 1807 and was the first to have passengers. The city’s location along the river also made Swansea a major port of great significance throughout the United Kingdom.

Swansea Population Growth

Between estimates taken in 2015 and 2016, the population of Swansea grew almost 1%, a higher increase than annual growth each year from 2011 through 2015. About 2,200 people migrated to Swansea between 2015 and 2016, while there were slightly more deaths than births during the same period. The primary reason for growth was international migration, while some growth was observed from migrants of Wales. Though growth has been slow, it is expected to remain steady in the area in future years. The city’s population growth has exceeded the growth observed in Wales, but falls below the national average in the United Kingdom.
