The provided line graph illustrates the birth and death rates in a major country over a span of fifty years, from 1970 to 2020. Overall, both rates exhibit similar trends throughout the period, with notable peaks and subsequent declines.
Initially , the birth rate was at 2.5% in 1970. It experienced a slight increase over the following years, reaching its peak at 3.6% in the mid-1980s. This marked the highest point for the birth rate during the entire period. However, from 1990 onwards, the birth rate saw a significant decline, ultimately falling to just below 2.2% by 2020.
Conversely , the death rate started at a lower point of 1.2% in 1970. It rose gradually, peaking at 2% in 1990, which was the highest recorded death rate in this fifty-year span. Post-1990, the death rate decreased steadily, reaching 1.6% in 2000, 1.4% in 2010, and settling back to 1.2% by 2020.
In summary, both the birth and death rates peaked around 1990 and demonstrated a declining trend towards 2020, indicating significant demographic changes over the fifty years.
