Trends and statistics Statistics are the numbers which record facts (like the number of births and deaths in a year) and words that describe these numbers in relation to the whole group. 113 fishing boats were lost at sea last year. 20% of the fish population is currently at risk of disappearing. The majority o f our electricity could be generated by wave power. Trends describe patterns o f change in social behaviour or environmental conditions over a period of time and may tell us how much they have changed. Since 2009, interest in wave power has increased significantly. There has been a dramatic rise in fish farming over the last ten years. During this century there has been an upward trend in global temperatures.
