As mandated by the U.S. Constitution, America gets just one chance each decade to count its population. The U.S. Census counts every resident in the United States. It is mandated by Article I, Section 2 of the Constitution and takes place every 10 years. The data collected by the decennial census determine the number of seats each state has in the U.S. House of Representatives (a process called apportionment) and is also used to distribute billions in federal funds to local communities.

Since the 1990s Kern COG has maintained a regional travel demand model and socio-economic forecast. The program uses data from local, state and federal surveys, a regional traffic count program and a regional land use model. To minimize duplication of effort, the Kern COG modeling program is guided by a memorandum of understanding among Kern COG’s member agencies. Modeling is performed as a service to those agencies, and to meet state/federal requirements. Contact Ed Flickinger for more information.

The Kern Council of Governments, through an agreement with the California State Department of Finance, Demographic Research Unit, functions as the Affiliate State Census Data Center for the Kern region. Kern COG maintains a repository for current and past Census data. The executive director acts as the Census Bureau’s “key person” for Census-related activity. Kern COG is also the official source of demographic data for the County of Kern and its various departments.
Information is displayed on the Kern COG web site, and staff responds to more than 1,500 inquiries annually for Census and other information from private businesses, other government agencies and the general public. While many of these requests are routine, such as county population numbers, others involve detailed analysis of existing data and require extensive data compilation and mapping.
Kern COG staff also produces detailed maps that include Census data layers used for regional demographic analysis.

Since the mid-1990s, Kern COG has assisted local agencies in developing their GIS infrastructure. These systems are vital to the decision making that local governments carry out in their programs every day. Eighty percent of all local government data could be maintained more accurately and displayed more meaningfully through GIS. Local governments using GIS benefit from better decisions provided by the information available on these maps. The Kern Geographic Information Network (Kern GEONET) is a consortium of local governments administered by Kern COG. GEONET coordinates GIS development locally, saving cities more than $2 million from the joint purchase digital aerial imagery and creation of other data layers.
Kern COG has signed long-term agreements with some local government agencies to assist them in developing and maintaining their GIS. These custom agreements provide expertise and stability for smaller agencies more vulnerable to staff turnover. The GIS Incubator program assumes that as local agencies grow, they will be weaned off the need for Kern COG’s assistance. Maricopa, Wasco, Shafter, Kern County Community Development Department, Bakersfield Economic Development Department, Kern County Community Development Department and the Eastern Kern County Resource Conservation District are a few of the agencies that Kern COG has assisted with developing GIS. Kern COG also helps develop standards to increase data sharing benefits and publish data on the Internet to reduce public inquiries for data.

Interactive transportation maps showing thousands of traffic counts on local roads throughout the Kern Region from the 1990’s to today. The traffic count map includes forecasted traffic growth from the Kern COG regional travel model. To forecast total volume of a road segment, we recommend using the forecasted growth increment from the model and adding it to the most recent traffic count for a road segment. For guidelines on use of the Kern COG regional travel model go to the Transportation Model Documentation . For socio-economic data used in the travel model go to Maps and Data .
