The graph below shows the consumption of fish and some different kinds of meat in a European country between 1979 and 2004.
Fish and meat consumption
The line graph shows the weekly per-capita consumption of fish and three other meats in a single country in Europe between 1979 and 2004.
Overall, while the consumption of both beef and lamb reduced significantly during the 25-year period, that of chicken soared. Fish consumption, on the other hand, did not change much.
Despite a handful of large fluctuations, beef remained the most commonly consumed meat before 1989, averaging 180 to 240 grams per person per week. Consumption then dropped sharply to roughly 120 grams by the end of the period. The amount of lamb eaten every week also went into sharp decline, dropping from second place in 1979 at 150 grams to third in 2004 at roughly 70 grams.
Chicken consumption was slightly below that of lamb in 1979, at nearly 150 grams per person per week, but surpassed it by 1980. It then skyrocketed, overtaking that of beef by 1989 and eventually reaching nearly 250 grams by 2004. In contrast, although less fish was consumed than any of the other meats throughout the period, its consumption level was fairly stable, hovering around 50 grams the entire time. (190 Words)

How to Avoid Repeating ‘Per Person Per Week’
You need to first establish the context. In the first paragraph, I have “the graph shows weekly per-capita consumption”. Having established the context, you don’t necessarily need to repeat “per person per week”.
