St. Petersburg Population Growth

The reported population in St. Petersburg near the time of original incorporation - 1890 - was around 270 residents. By 1920, this number had grown to over 14,000 residents. By 1930, the population had more than doubled. This trend of intense growth continued over the years for some time. However, following 1980, the population came to something of a standstill until the year 2000. The population grew once more by another 10,000 individuals, only to see a decline at the next census that was taken in 2010. As the year 2020 comes closer - we see a slight uptick in the St. Petersburg population - but only time will tell if it will be maintained.

St. Petersburg was incorporated as a town on February 29, 1892, when it had a population of only some 300 people. However, St. Petersburg was not incorporated as a city until June 1903.

The nearby water channels were soon dredged to create a more easily accessible channel, and the port in the area proliferated - bringing work for residents and drawing the attention of those looking for steady employment. The population of the city soon began to increase, and this brought more improvements to the area. Soon, the first trolley service was installed in the city of St. Petersburg, and by 1915 the city had established its library. This library still stands today.
