Being 54.3% Hispanic, Osceola is one of three Hispanic-majority counties in Florida, owing to its large Puerto Rican American population.

Since the late 20th century, Osceola County has experienced a significant influx of migrants from the Commonwealth of Puerto Rico, the unincorporated territory of the United States,[5] and in the 2000 U.S. Census Puerto Rican was the largest self-reported ancestry group.

Voters approved the County Charter in March 1992, and it took effect on October 1, 1992.

Under State law, the County Commission is responsible for funding the budgets of all Osceola County Government, including the independently elected Constitutional Officers and Judicial Officers, as well as the Commission's own departments.

As of the 2020 United States census, there were 388,656 people, 109,642 households, and 81,168 families residing in the county.

Instead, Osceola patrons were taken care of by Orange County Library System.

In 1968, the location moved to a 4,000 square foot building on Broadway and Dakin.

Hart Memorial Library is the Osceola headquarters and is now located in a 43,000 square building .

Veteran's Memorial Library was at first a reading room until enough funds were raised to build the first official location on Massachusetts Avenue in Saint Cloud.

In 1995, this branch moved for its final time to a larger building on Indiana Avenue and 13th street where it is still located today.

This branch was eventually moved into a larger location with a collection of 40,000 books and computer access for patrons.

Osceola Library Systems began as an independent organization on April 1, 1989.

[21][22] Back in 2009, there were plans to create a new city named Destiny near the intersection of the Florida Turnpike and US 441.

The project was halted by The Florida Department of Community Affairs after concerns that there would be mass urban sprawl.
