Band 6+: The line graph below shows the life expectancy at birth in four countries between 1960 and 2020. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The line graph illustrates the life expectancy at birth in four different countries, Japan, the UK, Brazil and Nigeria between 1960 and 2020.

As an overview, it can be clearly seen that Japan had the highest recorded life expectancy at birth during the period, whereas Nigeria accounted for the lowest proportion of lifespan over the period. One common thing is similar in four countries that increasing the life expectancy rate.

It is immediately apparent from the graph that, Japan accounted for the highest average lifespan around 68 years in 1960, then crossed in 1970, with the UK at 72 yeras. After that, life span rate of Japan increased considerably to 85 years in 2020. Similarly, the UK recorded life expectancy rate at 71 years in 1960, then rapidly increasing to 81 years in 2020.

Moving on to the remaining details, in 1960, Brazil had recorded average life span at 54 years, after that significantly increased to 76 years of life expectancy rate in 2020. Likewise, Nigeria had accounted for the least recorded at 37 yeras average life rate in 1960, and gradually increased to 55 years in 2020.
