The phrase "year by year" is often used when we talk about something that changes gradually over time. For example, we might say "year by year, the number of people using public transportation is increasing" or "she watched the flowers grow year by year in her garden." Essentially, "year by year" means "little by little over the course of many years." It's a good way to describe slow, steady changes over a long period of time.
