2. Introduction

One of the goals of the 2020 Census is to generate the largest possible self-response rate, which will reduce the need to conduct expensive, in-person follow-up with nonresponding households. Contact strategies will encourage the use of the internet as the primary response mode through a sequence of invitations and postcard mailings. Households will be able to respond using multiple modes (i.e., internet, paper, or telephone, if they call the Census Questionnaire Assistance [CQA] Center). Furthermore, respondents will be able to submit a questionnaire without a unique identification code.

The 2018 End-to-End Census Test is an important opportunity for the Census Bureau to ensure an accurate count of the nation’s increasingly diverse and rapidly growing population. It is the first opportunity to apply much of what has been learned from census tests conducted throughout the decade in preparation for the nation’s once-a-decade population and housing census. The 2018 End-to-End Census Test will be held in three locations, covering more than 700,000 housing units: Pierce County, Washington; Providence, Rhode Island; and the Bluefield-Beckley-Oak Hill, West Virginia area.

The 2018 End-to-End Census Test will be a dress rehearsal for most of the 2020 Census operations, procedures, systems, and field infrastructure to ensure there is proper integration and conformance with functional and non-functional requirements. The test also will produce prototypes of geographic and data products. Note that 2018 End-to-End Census Test results are based on three sites that were purposely selected and cannot be generalized to the entire United States.

This study plan documents how the response rates from the 2018 End-to-End Census Test will be assessed, as guided by questions to be answered.

3. Background

The following section provides a summary of contact strategies tested throughout this decade and the response rates associated with them. Data are presented for the 2012 National Contact Test, the 2014 Census Test, the 2015 National Content Test, the 2016 Census Test, and the 2017 Census Test. This section concludes with a discussion of the contact strategy plans for the 2018 End-to-End Census Test.

1. 2012 National Content Test

The 2012 National Content Test (NCT) played an early role in 2020 Census planning. The sample was selected from housing units in mailout/mailback¹ areas from the 50 states and the District of Columbia. This sample of 80,000 housing units was randomly assigned to one of six contact and notification strategy panels to determine the best “Internet Push” methodology that would get respondents to complete the test census online (Bentley and Meier, 2012). These six panels are outlined in Table 1.

The 2012 NCT results showed variation of self-response rates across panels and modes. (See Table 2). Panel 6 experienced the highest overall self-response, while Panel 3 had the highest internet response.

2. 2014 Census Test

The 2014 Census Test was a site test conducted within a number of census blocks delineated from areas in the District of Columbia and Montgomery County, Maryland. This test examined eight contact strategies for optimizing self-response including preregistration, internet response without an ID, and email invitations in lieu of mail. The goal was to determine which panel best encouraged internet response. Table 3 summarizes the experimental panel design:

Note: Households in Panel 1 that do not preregister by 6/18 will receive the M1 panel materials.

Response rates were the primary analytical measure used to evaluate the success of the different contact strategy panels. Panel 5 produced the highest self-response rate and the highest internet response rate. Table 4 shows the total response rates for each panel.

3. 2015 National Content Test

The 2015 National Content Test (NCT) was conducted with a nationwide sample of 1.2 million

housing units including Puerto Rico. The 2015 NCT focused on content testing, testing different contact strategies aimed at optimizing self-response (OSR), and testing different approaches for offering language support in mail materials.

The OSR research conducted in the 2015 NCT compared nine contact strategies that differed in the timing and content of contacts. It also compared three language panels with different designs for bilingual mail materials. For the OSR sample, the probability of selection for each housing unit was dependent on tract-level data regarding the number of residential fixed high-speed Internet connections reported by the Federal Communications Commission (FCC) and the Low Response Score (LRS) from the Planning Database² (PDB) (Mathews, 2015). Table 5 summarizes the contact strategy panel design, and Table 6 summarizes the three language panels.

Table 7 shows the self-response rates, overall and by mode, for each of the contact strategy panels in the stateside portion of the NCT sample. Panel 6 had a significantly higher overall response rate than all other panels. Panel 8, which did not have the option of responding by mail, had a significantly higher internet response rate, but a significantly lower overall response rate than all other variations of the Internet Push panel with the exception of Panel 4

4. 2016 Census Test

The 2016 Census Test was a site test, so all sampled housing units were geographically clustered in Harris County, Texas, and Los Angeles County, California. One of the objectives for the 2016 Census Test was to experiment with methods of maximizing self-response. Each strategy was designed to increase the number of households that responded online and to gain the cooperation of respondents who speak languages other than English. Four of the five panels incorporated the Internet Push approach in which sampled housing units did not receive a paper questionnaire in the first mailing. The fifth panel represented the Internet Choice option for respondents who received in the first contact both the paper questionnaire and the explanation of the choice to respond on the internet. The full contact strategy panel design is summarized in Table 8.

All housing units in the two selected sites were assigned to a language stratum and to a response stratum. The language stratum was assigned through the use of a special tabulation of 2010-2014 five-year data collected by the American Community Survey. The three response strata represented an estimated Low, Medium, or High likelihood of responding. The likelihood of a particular case to respond was calculated by combining data from the FCC with information about 2010 Census mail return rates. More details about how the sample for the 2016 Census Test was selected can be found in the sample design specification (Konya, 2016).

Table 9 shows the combined response rates for both sites. Overall, the 2016 Census Test had a response rate of 45.9 percent, and the internet response rate was 30.3 percent. The panel with the highest response rate and the highest internet response rate was the Internet Push with the language insert panel, 47.8 percent and 34.7 percent respectively. The Internet Push panel had the lowest response rate of 43.8 percent.

5. 2017 Census Test

The 2017 Census Test sampled 80,000 housing units across the nation with a Census Day of April 1, 2017. One objective of the 2017 Census Test was to measure consistency and accuracy of responses to questions asking about household members’ enrollment in American Indian or Alaska Native entities. A household was sampled into one of four panels and received up to five mail packages inviting response to the 2017 Census Test. Table 10 summarizes the mailout strategy for the 2017 Census Test.

6. 2018 End-to-End Census Test

The 2018 End-to-End Census Test will be held in three locations, covering more than 700,000 housing units: Pierce County, Washington; Providence, Rhode Island; and the Bluefield-Beckley-Oak Hill, West Virginia area. Although they are not part of a designed experiment, the test will include two mail panels, three different “mail cohorts” that will be mailed the Internet Push mailings at different times, as well as bilingual and monolingual mail panels. See Table 12 for a description of mail panels and mail cohorts.

7. Response Rate Mapping Application

In 2010, the Census Bureau used the Take 10 Map to communicate to the public daily decennial self-response rates at different geographic levels. The 2010 Census Take 10 Map was used by the public to promote census participation, for example, by fostering competition between communities. Figure 1 displays a screenshot of this map.

While a similar application will not be available for the 2018 End-to-End Census Test, the Census Bureau plans to build an online, interactive mapping tool for use during the 2020 Census. The planned application will track self-response rates by mode across geographies as well as provide underlying self-response rate data to the public via an application programming interface (API). An internal test after the 2018 End-to-End Census Test will be conducted to ensure all systems for displaying public response rates on a daily basis during the 2020 Census are working properly.

Figure 1. Screenshot of 2010 Census Take 10 Map

4. Assumptions

The assumptions for the Response Rates Assessment are:

• The 2018 End-to-End Census Test will consist of three test sites, but only the Providence County, Rhode Island site will have a self-response option.

• Self-response data collection will occur between March 16, 2018 and July 31, 2018.

• Update Leave will be conducted between April 9, 2018 and May 4, 2018.

• All mail returns and Undeliverable as Addressed (UAA) will have a check-in date.

• Field work for the Nonresponse Followup (NRFU) operation will be conducted between May 9, 2018 and July 24, 2018.

5. Questions To Be Answered

The questions to be answered in the Response Rates Assessment are:

Research Question #1: What were the response rates by mode and overall?

Research Question #2: What were the daily response rates by panel, cohort, mode and overall? What impact did each mailing have on the daily response rates?

Research Question #3: What were response rates by mail panel, mail cohort, and language of mailing? How did response rates vary across self-response modes?

Research Question #4: What were the demographic and housing characteristics of respondents across mail panel, mail cohort, and language of mailing?

Research Question #5: What device types did Internet respondents use to complete the form?

Research Question #6: Is the API prepared to provide data for the response rate mapping application in the 2020 Census?

6. Methodology

The primary measure calculated for this study will be a self-response rate. The overall self-response rate is a measure of respondent cooperation and reflects the sample housing units that respond to the survey by one of the three response modes: (1) responding online to the internet survey site, (2) providing information to a phone interviewer via Census Questionnaire Assistance (CQA), or (3) completing and returning the mail questionnaire. By definition, the self-response rate is the number of responses received by any self-response mode divided by the number of sampled housing units.

Overall self-response rate =	Unduplicated sufficient responses (internet, CQA, or mail)	* 100 percent
	Total sample size

Households providing more than one self-response are counted in the response rate calculation only once. A response is sufficient if at least two household-level items or at least two of the following person-level items are provided: name, age/date of birth, sex, race/Hispanic origin, or relationship.

The self-response rate by mode is similar to the overall self-response rate, but it focuses on each individual response method rather than combining them together.

Internet response rate =	Unduplicated sufficient internet responses	* 100 percent
	Total sample size

CQA response rate =	Unduplicated sufficient CQA responses	* 100 percent
	Total sample size

Mail response rate =	Unduplicated sufficient mail responses	* 100 percent
	Total sample size

Examples of demographic, response rate, and device type tables appear in Appendix A, Appendix B, and Appendix C.

7. Limitations

The limitations for the Response Rates Assessment are:

• The response rates from the 2018 End-to-End test are not generalizable to the entire country or to the 2020 decennial census environment.

• Timing of mailed responses may not accurately reflect respondent behavior on a daily basis.

8. Measures of Success

• A higher percentage of respondents use the Internet rather than CQA or paper questionnaire to respond.

• Increases in the daily response rates occur around the time the mailings arrive in potential respondents homes.

• Peak reaponse rates are spread evenly across mail cohorts.

• Respondents completing a questionnaire by Internet, CQA, or paper questionnaire are not enumerated in NRFU.

9. Data Requirements

The following list describes data requirements that will be needed to answer the research questions in the Response Rates Assessment. These requirements are specific to this assessment and are in addition to any global data requirements.
