Valencia enjoyed strong economic growth over the last decade, much of it spurred by tourism and the construction industry,[citation needed] with concurrent development and expansion of telecommunications and transport. The city's economy is service-oriented, as nearly 84% of the working population is employed in service sector occupations[citation needed]. However, the city still maintains an important industrial base, with 5.5% of the population employed in this sector. Agricultural activities are still carried on in the municipality, even though of relatively minor importance with only 1.9% of the working population and 3973 hectares planted mostly in orchards and citrus groves.
