Elements of Multi-Channel Data Collection • Paper - Traditional survey vehicle - The ultimate contingency plan • Internet - Lower cost - Easier to use - More accurate • Telephone - Primarily help and assistance - Fulfilment (additional questionnaires, language guides) - Response for people with special needs - Resolution of incomplete forms • (Field) personal enumeration - Most expensive part of a Census - Mostly manual - Could benefit from automation - Current trend toward Mobile Phones and PDAs 11/1/2021 © 2008 Lockheed Martin Corporation.

Independent Channels • Approach - Independently developed capture channels • Advantages - Allows optimization of each channel - Adapts to legacy capture systems • Disadvantages - No integration - Modal bias! - Significant integration effort 11/1/2021 © 2008 Lockheed Martin Corporation.

Internet-Centric Products • Approach - Web-based Solution at center of architecture - Internet • Core of architecture - Telephone • Agents use Intranet applications - Paper • Form design adapted from internet design with additional attributes - Field • Based on Internet design • Advantages - Integrated Approach – avoids modal issues - Well suited for Internet and Telephone capture • Issues - May be suboptimal for paper - Field (PDA) and Internet not always compatible - Infrastructure Costs (hardware and software) - Scalability? 11/1/2021 © 2008 Lockheed Martin Corporation.

Issues with Multi-Channel Data Collection • Modal Bias - Question interpretation and response must be the same across modes – modal difference • Security - Internet – Hacking, Denial of Service, etc. - Paper – Anthrax, Risen, other NBC threats • Authentication - Does the respondent represent the household? • Duplicate Resolution - More channels, especially electronic, mean more duplicate responses • Receipt Control - Knowing the state of responses from creation to data delivery • Management Information - Having the information to manage the Census enterprise 11/1/2021 © 2008 Lockheed Martin Corporation.

Conclusion • Census isn’t as simple as it seems - Capturing all the data, accurately and delivering on time is hard • Multi-Channel Census Data Collection must address many issues - Completeness - Scalability - Data quality and consistency - Security and authentication - Channel data integration - Management information • It takes planning, the right solution and census experience to be successful! 11/1/2021 © 2008 Lockheed Martin Corporation.
