Lake Nona Medical City is considered a biomedical research and educational hub since it includes the University of Central Florida College of Nursing and the University of Central Florida College of Dental Medicine, Sanford-Burnham Medical Research Institute, the Orlando Veterans Administration Medical Center, Nemours Children’s Hospital, and a University of Florida Academic and Research Center. In the Lake Nona area, the population has grown from merely 1,500 in 2000 to over 50,000 people in 2015. In just the past 5 years alone, the population increased from roughly 27,000 people, nearly doubling. Some statistics show that by the 2020 census, the Lake Nona area population could be as high as 75,000, while others put the figure more or less around 100,000 strong, with the latter statistic becoming more practical due to the fact that there are nearly 20,000 homes under construction or planned in the Lake Nona area. Most of the newcomers here are very affluent and in the upper middle class, settling for the proximity to Orlando's emerging Medical City in Lake Nona. During the Puerto Rican crisis of 2015, over 15,000 Puerto Ricans called Orlando their new home while about 20% of those settled in the Lake Nona area.
