Small Area Economic Data from the 2007 Economic Census and Economic Surveys APDU Annual Conference The Brookings Institution Thursday, September 24th, 2009 Presented by: Andrew W Hait and Patrice C. Norman U.S. Census Bureau Economic Planning & Coordination Division
Economic Surveys vs. the Census • Economic Indicators • Very timely • Limited data items • Limited NAICS and Geo levels shown • Economic Surveys • Mostly annual • Slightly more data items and more NAICS • Still limited in Geo levels shown
The Economic Census • The preeminent supplier of extremely detailed data about the US economy • Over 1,100 unique data items tabulated and disseminated • Over 2,100 NAICS industries published at 2- thru 6-digit NAICS levels • Over 15,000 unique geographic areas disseminated
Economic Census Geographies • United States • States and equivalents • Metro Areas • Counties and equivalents • Places (cities, towns, villages, etc.) • Consolidated Cities • Independent Cities • Part-Places • “Balance of Counties” • Regions and Divisions • Puerto Rico Commercial Regions • ZIP Codes
Issues with 2002 and Prior Censuses • Only included incorporated places • Large percentage of suppressed or dropped places due to small size of qualifying places • Places with high econ activity but low population missed
Selected Findings from the 2002 Economic Census • For the Retail Trade sector • Almost half of the states had more than 25% of their establishments tabulated in the “Balance of County” and 10 had over 50% • For the Manufacturing sector • 23% of the places nationwide were suppressed at the 2-digit NAICS level, with 94% of these reporting < 5,000 employees • For Maryland (all sectors) • < 1% of the published data were in places that would be dropped if changed qualification criteria
Changes for the 2007 Economic Census • Census Designated Places (CDPs) now included • Significant econ activity in CDPs • “Penalized” states with small number of incorporated cities • Population cutoff standardized • Was 2,500 in most of US and 10,000 in “strong” Minor Civil Division states; Now 5,000 for all states
Changes for 2007 (cont.) • Jobs criteria added • Places with 5,000 or more jobs also now included (just over 100) • Commerce, Industry, and Vernon, CA previously covered in the Economic Census • Lake Buena Vista, FL (16 pop; 30,768 jobs) • Geocoding to places “universe” as well as to Economic Places • Will allow us to do special tabs of places with high employment but didn’t make the cut using sometimes old Pop and Jobs data.

2002 Economic Census Data Release Schedule • Industry Series:Selected national-level industry and product data by sector and industry (4/09 - 12/09) • Geographic Area Series: Selected national-, state-, and other geographic-level data by sector, industry, and geography (11/09 – 8/10) • Subjects and Summary Series: Selected summary data by sector (including Products, Size, and Misc. Subjects reports) (10/10 – 6/11) • ZIP Codes: Number of Establishments by sales size for selected sectors (7/11)
County Business Patterns • Provides statistics annually at a detailed geographic level • Number of Establishments, Employment, First Quarter Payroll, and Annual Payroll • 2- thru 6-digit NAICS levels • US, State, County, and Metro Area levels • For 2007: • Number of Establishments – 7,705,018 • Employment – 120,604,265 • First Quarter Payroll - $1,274,971,624 • Annual Payroll - $5,026,778,232
Noise Infusion for 2007 CBP • Data perturbed at the establishment level by applying a noise multiplier • Done prior to tabulation • Applied to all data cells except Number of Establishments • Results in a relatively small change in vast majority of data cells
Noise Infusion Results • No need to apply Complementary cell suppressions • Has resulted in 10% more published data at the U.S. level for the 2007 CBP vs. the 2006 CBP • More significant impact at the State, Metro Area, and County levels
Noise Infusion (cont.) • Noise flag disseminated for each published data cell except Number of Establishments • “G” = low noise (<2%) • “H” = moderate noise (>2% but <5%) • >5% - data suppressed in table
Upcoming CBP Enhancements • New Legal Form of Organization breakout • Planned for 2008 CBP • Island Area expansion • Current CBP only covers Puerto Rico • Expansion will incorporate other 4 Island Areas into data products • American Samoa, Guam, Northern Mariana Islands, and the US Virgin Islands
Nonemployer Statistics • Provides statistics annually at detailed industry and geographic levels • Number of Firms and Receipts • 2- thru 6-digit NAICS levels • U.S., State, County, and Metro Area levels • For 2007: • Number of Firms – 21,708,021 • Receipts - $991,791,563 • Noise Infusion debuted with the 2005 Nonemployers data
