The provided graph depicts the shift of the UK’s population over a span of 9 years starting from 1999. In general, despite showing wild vacillation, the rates of 2 types of migration (immigration and emigration) were on the rise. The discrepancy between these 2 data also followed a similar trend. Looking closely at the lines, it is clear that the number of people entering and leaving the UK had gradually increased within a decade. In particular, the figure for immigration commencing at slightly above 450000 slowly climbed up to over 500000 in 2003 before soaring up to merely 600000 one year later. Since then, there had been a stabilization in this data until 2005. Similarly, starting at about 300000, the statistic of emigration surged to precisely 400000 in 2006, from which the figure dropped by 50000 before peaking at roughly 430000 in 2008. As a result of the fluctuation of the migration, the net value underwent the same tendency. This figure had a starting point of well above 150000 and remained unchanged for half a decade. Afterward, the spike of immigration in 2004 caused the difference value to go up to almost 250000, then it steadily declined to roughly 160000 in 2005, though there was a boost of approximately 25000 one year prior.
