Trenton Population Growth

In its earliest years, Trenton saw its population grow at a steady rate. However, during the 20th century, this population began to slow. The population peaked at 128,009 at the time of the 1950 census. However, after this, the population has only continued to drop at each 10-year census. Recent estimates show that the population had dropped 1% since the last census in 2010. High crime rates are a contributing factor to the loss in population, although the numbers have gotten better in more recent years. Perhaps with continuous efforts to revitalize the city and bring crime down further, Trenton’s population will once again rise.
