The diagrams present information about marriage rates in Japan. While the table illustrates how the percentage of unmarried 50-year-old adults changed over five decades, 1970-2010, the line graph represents the changes in marriage and divorce numbers from 1970 to 2016.
Overall, it is readily apparent that the proportion of 50-year-old Japanese adults exhibited a consistent increase over the given period. Meanwhile, opposite trends were observed in marriage and divorce rates, with marriage rates showing an overall decline.
According to the table, there was a continuous incline in the proportion of adults who were never married in Japan. Standing at a meager 2 percentage-point in 1970, this figure then reported a doubling the following decade. The third decade saw further increase to 7 percentage-point, which eventually more than doubled with a staggering 15 percentage-point in the final decade.
The analysis of marriage and divorce portrayed a reversed pattern. Although the number of marriages at the start of the period was an impressive 1.000.000, it fell significantly to 600.000 in 2016. As for the divorce rates, the number experienced a more than twofold growth, increasing from the initial 100.000 to approximately 230.000 at the end of the span.
In summary, it is sensible to conclude that over given period, the Japanese marriage rates continued to decline, leading to a rise in the number of divorce cases.
