Map of the Month

Smoking in California

For April's map series, the CED looked at the counties of California that may be most affected by Proposition 56, which went into effect on April 1, 2017. This proposition increased the tax on tobacco products from $0.87 to $2.87, and changed the tax's revenue allocation to support existing state healthcare programs. To study the effects of smoking across California counties, we looked at each county's overall percentage of residents who smoke, as well as each county's mortality rate from lung cancer.

Crime Changes in California, 2009-2015

For March's newsletter map, the CED performed a deep-dive into county-level crime data to shed light on changes in crime rates and the potential effects of recent public safety legislation on rural northern California counties. Between 2009 and 2015, crime rates in most California counties did increase relative to national averages, with the highest increases felt in rural parts of the state. While it is important to remember that correlation does not always imply causation, this time period does coincide with the passage of Assembly Bill 109 and Proposition 47, two controversial measures aimed at reducing state prison populations.

Net Migration By County, 2010 - 2015

Timber and Trash: A Look at Natural Resources for Earth Month

The timber as a percentage of all natural resource and agricultural production map shows how vital timber production is for many northern California communities. The waste disposal sites by facility type map shows how communities throughout the state are affected by waste management. Beyond allowing us to visualize how waste might be moving from our State’s larger population centers to more rural disposal sites, it also suggests a lack of options for specialized sites such as green waste or chipping and grinding facilities within our region.

Agricultural Employment and Irrigated Cropland in California

 It is important to note that overall agricultural land use is much greater in most locations, as this figure does not include lands irrigated by private wells or fields not requiring irrigation. Statewide, San Joaquin County has the highest amount of its land area dedicated to irrigated croplands at 53.1 percent, followed by Stanislaus County at 44 percent. Counties on the westward (drier) side of both the San Joaquin and Sacramento valleys tended to have the highest amounts of land area dedicated to irrigated cropland. Within the CSU, Chico Service Region, irrigated croplands accounted for a high of 41.1 percent of land in Sutter County, followed by 26.1 percent of land in Colusa County. With much of this irrigation dependent on reservoir storage and withdrawals from the Sacramento and Feather rivers, a strong rainy season and a return to normal snow packs in the Sierra and Coastal Range will be especially important to those counties.
