Deerfield Beach is a city in Broward County, Florida, United States, just south of the Palm Beach County line. The city is named for the numerous deer that once roamed the area. As of the 2010 United States Census, the population was 75,018. It is a principal city of the Miami metropolitan area, which is home to an estimated 6,158,824 inhabitants as of 2017.
Deerfield Beach's history dates to 1890, when a small settlement named Hillsborough was developed along the Hillsboro River. As the population grew to 20 by 1898, the settlement was now served by its own post office and the town was named Deerfield for the deer that grazed along the river.
By the early 20th century, as the town's population continued to grow, the Florida East Coast Railroad constructed tracks en route to Miami bisecting Deerfield. Deerfield's early settlers were mostly farmers who grew pineapples, tomatoes, green beans, squash and fished along the Intracoastal Waterway. Deerfield remained a largely agricultural community, but in 1939 the town's name was changed to Deerfield Beach to let tourists know it has a beach. In 1952, the original Deerfield Beach Pier was built of wood.
As of 2010, there were 42,671 households, of which 21.8% were vacant.
