The line graph illustrates the changes in the percentage of immigrants to a particular country from the UK, Asia and other regions between 1976 and 2011, as well as the overall total.
Overall, while the proportion of immigrants from the UK declined steadily throughout the period, the figures for Asia and other regions generally increased. As a result, despite some fluctuations, the total percentage ended slightly higher than its initial level.
In 1976, the UK was the largest source of immigrants, accounting for about 14%, compared to 11% from other regions and only 6% from Asia. However, the proportion from the UK fell consistently over the following decades, dropping to 10% in 1986 and then to just 5% by 2011, making it the smallest contributor at the end of the period. By contrast, immigration from Asia rose steadily from 6% in 1976 to around 10% in 1996, before climbing more sharply to 15% in 2011, becoming the dominant source. Similarly, the figure for other regions declined slightly at first, reaching approximately 8% in the mid-1980s, but then increased to a peak of 14% in 2006 before finishing at about 13%.
