As the fourth largest metropolitan area in the US, Dallas has become a dominant industrial and financial center. Anchored by a world-class international airport and host to over twenty four-year colleges and universities, the city offers a diverse mix of cultural activities, with a considerably lower cost of living when compared to other major cities. The unemployment rate is also significantly lower than the national average, currently at 5.1%. Contrary to popular depictions, the region is not entirely dominated by the Oil & Gas industry and has a diverse economy that is reflective of the nation as a whole, and the city has been dubbed
the "Silicon Prairie" to highlight the significant high technology activity in the area. Office space for rent in Dallas continues to be in high demand with its rich high-tech manufacturing base, bio-tech firms, information technology companies, and its large financial, insurance, and real estate services sectors. The city continues to be a desirable, attractive location for top talent, being home to 24 Fortune 500 companies. Commercial development, and thus the future of office space for lease in Dallas, has a strong outlook as the city continues to grow.
