DIVERSIFICATION VS. SPECIALIZATION ECONOMIC LANDSCAPE 30 T he following chart shows the distributions of those 21 industry sectors of the five metro areas by their output or contribution to Gross Regional Product (GRP). The significance of the oil and gas extraction in Corpus Christi and Laredo (shown in red) is apparent. In 2014, the mining sector contributed to about 8 percent of the total income earned in those two metro areas. The government sector is a major income generator in South Texas metro areas, contributing to more than one-fifth of all incomes earned in Brownsville, Laredo and McAllen.

Other than the government sector, those private industries contribute less to GRP relative to employment in the area economies. Annual Review of South Texas Economy
