Tourism is one of the staples of Florianópolis' economy. Many inhabitants and tourists consider Floripa to have a singular beauty endowed with strong lines of Azorean culture, observed in the buildings, workmanship, folklore, culinary and religious traditions. Its environmental restrictions on building and commercial development have been more or less strictly enforced, helping it to keep its original character.
Between 1970 and 2004, Florianópolis's population tripled, as did the number of shantytowns. But the local economy grew fivefold, and incomes grew in step. Opportunity seekers, urban and rural, white collar and blue, poured in. While many Brazilian cities are struggling to graduate from smokestacks to services, Florianópolis is succeeding. Thanks in part to a federal rule that for decades barred heavy industry on the island, town elders focused on cleaner public works which led to the founding of several public and private universities that make this one of the most scholarly cities in Brazil.
To meet the demands of its academic crowd, the city invested heavily in everything from roads to schools, and now Florianópolis ranks high on every development measure, from literacy (97 percent) to electrification (near 100 percent). By the late 1990s, private companies were flocking to the island, or emerging from a technology "incubator" at the federal university. (Among the innovations it hatched: the computerized voting machines that have made Brazilian elections fraud-free and efficient). Local officials now say their aim is to be the Silicon Valley of Brazil, with beaches.
In addition to its white sand beaches, Florianópolis offers many historical attractions, including the sites of the original Azorean colonists, the Lagoa da Conceição lagoon, and Santo Antônio de Lisboa. Tourism in Florianópolis has grown significantly over the past 10 years, with increasing numbers of visitors coming from other large cities in Brazil (particularly Porto Alegre, Curitiba, São Paulo and Rio de Janeiro) as well as other South American countries (particularly Argentina, with direct flights offered daily from Buenos Aires).
During the past several years, a greater number of international tourists have also begun to frequent the island (particularly from Europe and the United States). As the number of visitors grows each year, Florianopolis faces the ongoing challenge of ensuring that its limited infrastructure and resources are updated to adequately accommodate them. Of particular concern are the sewers, which often drain directly into the ocean, polluting the very beaches that attract so many visitors.
During the past decade technology and software development firms also experienced strong growth, and today Information Technology services are one of the top revenue generators in Florianópolis. Several technology centers are spread around Florianópolis, making the city an important pole in this economic sector.
The GDP for the city was R$ 6,259,393,000 (2005).
The per capita income for the city was R$ 15,776 (2005).
