The chart illustrates information about the rate of individuals with language-related problems over the last 30 years.
Overall, several clear trends and noticeable changes can be observed. It is clear that the rate increased steadily throughout the period, whereas no decline was recorded in any year. In general, the figure rose from the lowest point at the beginning to the highest rate at the end. These variations highlight major changes throughout the period.
To begin with, the lowest figures stand out, reflecting a notable increase in the rate of language-related problems. For example, the rate started at around 2 per 100,000 people 30 years ago and rose slightly to about 3 after five years. In contrast, the following years showed a sharper rise, reaching 7 fifteen years ago.
Moreover, clear differences between the earlier and later years can be observed. While the rate continued to increase gradually, it climbed from around 7 to about 8 ten years ago and finally reached 9 per 100,000 people at present. These comparisons make the upward trend more noticeable and highlight major changes in the data.
