Integrated Federal Statistical Data Access Calendar

The Integrated Federal Statistical Data Access Calendar (http://proximityone.com/situation/calendar.htm) covers all primary Proximity and Federal demographic-economic statistical release dates. It includes all Federal statistical data that feed into development of Proximity Decision-Making Information (ProximityDMI) resources including MetroDynamics, Situation & Outlook, CommunityViewer GIS, DMIGateway and related estimates and projections.

 

This version of the calendar includes (from current date forward):

Proximity scheduled statistical release dates & meeting events into 2011
Selected related non-Federal statistical release dates and meeting events into 2011
All primary Federal statistical demographic-economic statistical release dates for the year ahead

   (more extensive than OMB's annual calendar of principal economic release dates)

Selected Census Bureau statistical program (ACS & Census 2010) anticipated release dates into 2012

   (more extensive than Census Bureau's multi-divisional release date schedules)

 

Federal statistical agency abbreviations referenced in the calendar include:

Bureau of the Census (Census)
Bureau of Labor Statistics (BLS)
Bureau of Economic Analysis (BEA)
Energy Information Administration (EIA)
Federal Reserve Board (FRB)
Federal Housing Finance Agency (FHFA)
National Agricultural Statistics Service (NASS)
National Center for Education Statistics (NCES)

 

See Using the Calendar for more information.

 

County Monthly Employment and Unemployment Trends

Use County Monthly Employment and Unemployment Trends tools and resources (http://proximityone.com/county_employment.htm), updated monthly, to learn about employment and unemployment trends in your counties of interest. What trends will change when and where? How will this impact you?

 

Each month Proximity develops an extract file from the MetroDynamics (MD) database focused on county employment and unemployment trends. The extract file includes monthly projections based on the county-level employment and unemployment data published monthly by the U.S. Bureau of Labor Statistics (BLS).  Projections are developed by Proximity using the MD Modeler, related data and multi-scenario assumptions. The MD extract data are integrated into a shapefile for visual analysis. The shapefile is added to a CommunityViewer GIS project to develop many different types of employment-unemployment geospatial analyses and maps. Unlike PDF and webserver maps, you can integrate your data with these tools to examine prospective future impact on your projects, programs and operations.

Use monthly ranking tables to examine overall U.S. county employment/unemployment patterns and trends or a specific state.  The graphics presented below illustrate use of the ranking tables selecting Arizona and ranking on the unemployment rate in descending order.  Data shown in these graphics are not seasonally adjusted.  May data are preliminary; April are reestimated with updated state controls and revised inputs.

 

 

GIS & GeoDemographics Webinars

Participate in an upcoming Webinar and learn more about using GIS and geodemographics -- for subject matter, geography and analytical applications of interest to you. Get answers to questions and tips that you can use. There is no cost to participate. View dates, topics and register at http://proximityone.com/webmeetings.htm.

 

Each Web Meeting is conducted as a structured informal presentation for approximately two hours. General GIS and geodemographics topics are covered in addition to focused topics. CommunityViewer GIS (CV) users may learn new methods or tips useful to CV ongoing use. Attend as many sessions as desired. Sessions use CV but topics covered apply equally to other GIS software. Get answers to questions about your GIS/geodemographic analysis applications.

 

CommunityViewer GIS -- Using the Shp2Shp Feature

Use the Proximity CommunityViewer GIS (CV) Shp2Shp (Shape-to-Shape) operation relate diverse and otherwise unrelated geographies with integrated demographics.

 

The Shp2Shp relational analysis feature provides many geospatial processing operations. Shp2Shp determines geographic relationships of shapes in two shapefiles and provides information to the user about these relationships. A simple example of a Shp2Shp operation is to answer the question -- which county(s) touch (are adjacent to) one that I specify? A more general version of this example is -- tell me which counties, places, census tracts or ZIP codes -- choose any one type of geography (that meet some query/specific condition) in one shapefile touch (are adjacent to) counties, places, census tracts or ZIP codes -- choose any one type of geography (that meet some other query/specific condition). The Shp2Shp operations enable the user to select the type of geospatial relationship to be applied from these eight options: equals, disjoint, intersect, touches, overlap, cross, within, contains.

 

Operational Example.  You have an application that requires you associate the census tract geocode with each address. You have geocoded a set of addresses, assigning latitude-longitude and creating a shapefile (with CV geocoder or obtained otherwise).  You are now able to map the address locations in the context of any other geography, such as census tracts.  

 

This view shows address locations (red markers, schools) in context of Dallas County, TX census tracts.

Address by pointer profiled; next view shows zoom-in

 

Census tracts now shown with green boundary with yellow labels (geocodes).

Address locations use larger red marker.

Streets added (not required).

 

Select Shapefile 1 (addresses)

Select match-to field from shapefile 1 (objectid)

Select Shapefile 2 (census tracts)

Select match-to field from shapefile 2 (ctidfp00)

Select relationship (intersect)

Click Find Matches ... process occurs ... matches shown in lower right grid ... optionally export correspondence list to Excel.

First column is shapefile 1 field; second column is shapefile 2 code.

Note this shows address objectid 6452 is located in census tract ctidfp00 4811300800

(confirm this by visual inspection in previous map view)

 

Note that a SQL-type selection query/constraint (1.3 and 2.3) could be applied to either shapefile -- including on certain addresses and/or census tracts that meet some criteria.

 

 
Other Application Examples. Any combination of point, line, or polygon shapefiles may be used. Application examples:

 

Which ZIP codes touch certain other ZIP codes.
Streets, pipelines, waterways, corridors passing through selected polygon area(s).
Housing structures/addresses with certain attributes contained within selected census blocks.
Census tracts intersecting a set of ZIP codes.
School districts adjacent to/intersecting/ other school districts.
Census block groups meeting certain demographic criteria wholly contained within a metro area.

 

Repetitive matching operations may be performed using different criteria. Matching shapes may be cleared each time or accumulated.

 

By specifying the visible extent (with respect to the map view) a small part of a shapefile with a much larger extent can be processed, accelerating match processing time.

 

Applications Gallery Updates

The Applications Gallery http://proximityone.com/gallery/guide illustrates wide-ranging applications and projects developed using CommunityViewer and related geodemographic-economic resources.   New and updated topics:

 

Census 2010/ACS

Census Day is April 1, 2010, and marks the reference date for Census 2010 data.   The Census Bureau American Community Survey (ACS) is now integrally linked with Census 2010.  The "Census 2010/ACS" DMINews section provides monthly highlights of current and pending developments regarding these programs.  The focus is on data access and use and to a lesser extent data development and related operations. Proximity will continue to maintain the decennial census focused Web pages Census 2000 and Census 2010.

 

See updated ACS and Census 2010 data release dates in the Integrated Federal Statistical Data Access Calendar (http://proximityone.com/situation/calendar.htm).  To view all relevant dates, use the search feature with keywords ACS or Census 2010 (see about calendar searching).

MetroDynamics - Situation & Outlook Quarterly Updates & Meetings

See the year-ahead schedule/planner for upcoming MetroDynamics (MD) and Situation & Outlook (S&O) quarterly release-access dates and quarterly meetings.  These dates are also included in the Integrated Statistical Calendar.

 

MD and S&O are continuously updated for the U.S. and each state, metropolitan area and county and released for client access on the quarterly schedule. MD and S&O offer the best, and unique, information resources to assess the existing geodemographic-economic situation and how, where and when characteristics and patterns are changing.

 

The quarterly release date schedule is coordinated with integration of the most recent EEE data summarized in the next item.

 

MetroDynamics Quarterly Establishments-Employment-Earnings Updates

MetroDynamics (MD) is updated with the detailed (subject matter data by maximum detailed NAICS category) 2008Q4 quarterly establishments, employment, and earnings (EEE) data based on employer reported data from the Bureau of Labor Statistics ES-202 program.   See description of subject matter included in MD.  MD provides quarterly time series EEE data from 2004Q1 forward, then making a 20 quarter series.  Use the optional MD feature to estimate suppressed data and use continuous quarterly measurements in your analyses.

 

High Level Industry Quarterly Economic Analysis Updates

HLIAnalyst integrated software and database enables uses to analyze county level quarterly economic high level industry trend data.  The quarterly updated database enables users to examine employer reported "ES-202" data on establishments, employment and earnings with only a 7-8 month lag from the reporting period.  Easy access to county (or custom aggregate) area economic trend data.  Supported with on-demand graphic analysis/charts and analytical operations such as location quotient analysis.

 

Examining City/Place Population Trends: 2000-2008 Using New Estimates

New Census Bureau July 1, 2008 official place-level population estimates reflect place boundaries as of January 1, 2008. The estimates include 19,496 incorporated places, areas of population concentration with state designated governmental authority, as well as other types of sub-county areas.

 

As of July 1, 2008, total estimated population in all U.S. 19,496 incorporated places was 190,029,231, or 62.5 percent of the total estimated U.S. population of 304,059,724.  Small town America -- 12,855 of these places have a July 1, 2008 population

under 2,500 and account for 9,487,718, or 3.12 percent of the total U.S. population.

 

Cities by population size:

Places 50,000 population and over -- 698

Places 25,000 to 50,000 population -- 673

Places 10,000 to 25,000 population -- 1,534
