The provided line graph illustrates the shifting demographic landscape between urban and rural populations globally from 1970 to 2020. Overall, the fifty-year period witnessed a dramatic increase in urbanisation, with the proportion of people living in cities rising significantly, while the rural population experienced a corresponding decline. Initially, in 1970, the majority of people resided in rural areas, making up 70% of the population compared to just 30% in urban centres. However, a clear reversal of this trend became evident by the turn of the millennium. By 2000, urban populations had grown to constitute 60%, overtaking the rural percentage, which had fallen to 40%. This pattern of urban expansion continued and accelerated in the subsequent years. By 2020, the urban population had reached its peak at 75%, representing a substantial growth from the starting point. Conversely, the rural population had shrunk to a mere 25%, highlighting a profound global migration towards urban lifestyles and opportunities over the observed period.
