State Legislative Districts (SLDs) are areas from which members are elected to state or equivalent entity legislatures. The state legislative districts include the Upper/Senate (SLDU) and Lower/House (SLDL) chambers of the state legislature. While this section focuses on Virginia, all aspects are transportable and apply to any state or region.

Notes on Using Data in Table As noted elsewhere, data in the table are sourced from the American Community Survey 2016 5 year estimates (ACS1216). These data are based on a sample of respondents to a 5-year survey spanning calendars years 2012 through 2016. The estimates are centric to 2014. These are the most recent data available as of December 2017 and will update with ACS 1317 estimates in December 2018. These data are estimates and subject to errors of estimation and other sources of error. That said, we have used these data over a very long period for wide-ranging geographic levels and find the estimates to be very good and accurate depictions of actual circumstances. Note that for areas 65,000 population and over, ACS 2016 1-year estimates (ACS2016) are available. The 1-year estimates provide a more current estimate and generally more accurate. The 1-year estimates are not available for SLDs but are available for states, larger metros and counties and all 115th CDs. For example, the ACS 2016 1-year total population estimate for Virginia is 8,411,808 (centric to 2016) whereas the ACS 2016 5-year total population estimate is 8,310,301 (centric to 2014 and vintage to use when comparing state to SLDs).

2016 State Legislative Districts .. goto top All 50 states, and D.C. and Puerto Rico, participated in Phase 4 of the Census Bureau Redistricting Program, as part of P.L. 94-171. All states and areas provided the Census Bureau with the 2016 election cycle boundaries, codes, and in some cases names for their state legislative districts. States provided updates for their boundaries used in the November 2016 elections for the session that began in January 2016. The Census Bureau develops standardized SLDU and SLDL shapefiles. The following states had changes to their state legislative districts for 2016: Florida (upper house only), Minnesota, Maryland (lower house only), Georgia (lower house only). As of 2016, the 6,558 state legislative districts in the U.S. are comprised of 4,629 lower/house chambers and 1,929 upper/senate chambers. Of the total state legislative districts, 1,257 are 100-percent urban (every census block comprising the district is urban), 19 are 100-percent rural, and 927 are less than 1-percent urban. Use the interactive table in this section to view, rank, compare state legislative districts by rural and urban population and geographic area. SLD Mapping and GeoSpatial Analysis Use GIS tools to visually examine U.S. or state by state legislative district patterns such as percent population urban. 2016 State Legislative District (SLD) boundaries used here are based on the TIGER/Line shapefiles. 2016 SLDs - Upper click graphic for view  2016 SLDs - Lower click graphic for view  Integrated Use of these Data Analytics Resources .. goto top Use of these SLD data analytics resources is centered on 1) knowing more what, where, when and how of demographic-economic attributes for one SLD, SLD geodrill-down and a set of SLDs and 2) conceptualized around strategies. These can be best understood through face-to-face sessions focused/presented in these contexts: - a lead that speaks to the broader geographic-demographic-economic framework - VA; VA in context of region & US - the metro in which presented -- an oral and connecting the parts review of this: - example: Richmond metro Situation & Outlook The following frames a dynamic presentation using the CDSLD VA GIS Project. 1) know your district (drill down to intersection), about other districts, how your district relates - a presentation about this sort of capability: what it is saying and how it can be used: - like http://proximityone.com/cdsld/vaslds035.htm (one for each participant) - why and how to use this: http://proximatyone.com/sld_va.htm#table ... and how to extend it 2) how Democratic Promise (DP) and other initiatives can blend/benefit with/from use of the tools, data and methods - as it relates to DP, this would involve adding DP addresses (with related actions) to the CDSLD_VA GIS project - where there activity, what seems to be working, where planned activity is located. - more broadly examples; showing where medicare recipients are at BG level rather than SLD level 3) how these data, tools, methods facilitates D wins in 2018 & 2019 - Analysis and data are summarized at the block and block group levels - models, with continuously updating data, are used to predict outcome for every VA election (at least SLD/CD/state - policy/action eg GOTV tools are integrated to show what impact what action/resource allocation has on each election Related Sections .. goto top Congressional Districts - CD Map Gallery - 2016 115th Congressional Districts interactive tables: ..
