  1. 2010 Local Update of Census Addresses (LUCA) Maryland State Data Center Annual Affiliate Meeting April 4, 2007

  2. How Is The Census Taken? Through Address Based Enumeration Compile a Master Address File (MAF) -an up to date inventory of known living quarters • Approximately 120 million addresses • Updated with: • Postal Service Delivery Sequence File • Pre-Census Field Address Listing • Local Address Review - LUCA • Every KNOWN address will be accountedfor

  3. Why are Finding Addresses Important? • Everyone wants to be counted – census counts are used for apportionment and redrawing political districts • MONEY – More than $300 billion in federal funds distributed every year based on census data • Better data – housing units and group quarters (nursing homes, prisons, dormitories) are geocoded to a census block.

  4. Why Such Low Participation? • Lack of Awareness • Lack of Understanding the Importance • Lack of Data • Lack of Resources • It’s Not EASY!

  5. Why is it so Difficult?Additions to the Housing Stock • New structures • Conversion of existing residential to multiple units • Conversion of non-residential • Rehab of abandoned/condemned • Mobile Homes

  6. Subtractions from Housing Stock • Demolished • Conversion of existing residential – combining units • Conversion to non-residential • Abandoned/condemned • Mobile Homes relocated

  7. Locating Group Quarters • College Dormitories • Correctional Facilities • Nursing Homes • Psychiatric Centers • Small Residential Care Units

  8. Why so Difficult cont’d Each address that is added, deleted or modified must be “geocoded” to the correct census block ! Your address list may appear in this format: 100 South Main Street, Anytown, Maryland 21111
