"description":"Employment Centers (outline/shaded) \u2013 identified as areas with a high concentration of employment based on SANDAG\u2019s 2016 employment inventory from Urbansim summarized to quarter-mile radius hexagons. Local-maxima were identified as starting points, and regions were grown to include neighboring hexagons meeting a minimum employment density threshold within an approximate 2-mile radius. The resulting boundaries were generalized (taking into account major barrier features such as topography and freeways) and used to select SANDAG Master Geographic Reference Areas (MGRAs) by activity-weighted (population and employment) centroid. Employment centers are ranked by Tier based on total number of jobs:  Tier 1: 50,000 or more jobs  Tier 2: 25,000 to 49,999 jobs  Tier 3: 15,000 to 24,999 jobs  Tier 4: 2,500 to 14,999 jobs",
