  1. Respondent Universe, Sampling Method, and Response Rate


The respondent universe for this study includes all residents of the United States who are age 18 or older. This universe is estimated at 253,881,929 individuals (the total US population minus the 22.4% who are minors), based on US Census population estimates from July 1, 2018 (https://www.census.gov/quickfacts/fact/table/US#). The sample sample will be drawn from the AmeriSpeak panel, which is maintained by NORC. It includes approximately 35,000 adult individuals who fit the study’s target criteria. Therefore, the number of individuals who have the possibility of responding to this survey is 35,000. See Exhibit 1.1 for a summary.

Sampling will be done through AmeriSpeak, a probability-based panel designed to be representative of the U.S. household population.


AmeriSpeak leverages the NORC National Frame, which provides sample coverage for over 97 percent of the U.S. households. The 2010 National Frame used a two-stage probability sample design to select a representative sample of households in the United States. The first stage—the sampling unit—is a National Frame Area (NFA), which is either an entire metropolitan area (made up of one or more counties) or a county (some counties were combined so that each NFA contains a population of at least 10,000). The largest NFAs with a population of at least 1,543,728 (0.5 percent of the 2010 Census U.S. population) were selected with certainty; these areas have a high-population density, and are dominated by tracts with street-style addresses. These areas contain 56 percent of the population within 8 percent of the geographic area of the United States. The remaining areas were stratified into areas where street-style addresses predominate, and the remaining areas, which are less likely to have street -style addresses. The latter stratum (“rural” areas) comprises 81 percent of the geographic area, but only 14 percent of the population.


Within the selected NFAs, the second stage sampling unit is a segment, defined in terms of either Census tracts or block groups, containing at least 300 housing units according to the 2010 Census. A stratified probability sample of 1,514 segments was selected with probability proportional to size. For most of the 1,514 segments, the U.S. Postal Service Delivery Sequence File (DSF) provided over 90 percent coverage of the segments in terms of city-style addresses that are geo-codeable. For the 123 segments where the DSF provided insufficient coverage, we enhanced the DSF address list with in-person listing. The National Frame contains almost 3 million households, including over 80,000 rural households added through the in-person listing.


See Attachment 4 for a full technical overview of NORC’s AmeriSpeak panel.


Exhibit 1.2 shows the distribution of the survey’s intended sample. A side-by-side comparison of AmeriSpeak’s panel composition with the demographic benchmarks established by the U.S. Census Current Population Survey (CPS) and the American Community Survey (ACS) illustrates AmeriSpeak’s sample representativeness. The data are weighted for active AmeriSpeak Panel households and the Census benchmark data sources.

The overall expected cumulative response rate for this study is 10%, based on NORC’s AmeriSpeak panel and prior nationally-representative studies completed within that panel. For survey completion, the expected rate is 35%. This particular study has not be conducted previously.


  1. Procedures for Collection of Information


The sample for a specific study is selected from the AmeriSpeak Panel using sampling strata based on age, race/ethnicity, education, and gender (48 sampling strata in total). The size of the selected sample per sampling stratum is determined by the population distribution for each stratum. In addition, sample selection takes into account expected differential survey completion rates by demographic groups so that the set of panel members with a completed interview for a study is a representative sample of the target population. If panel household has one more than one active adult panel member, only one adult in the household is eligible for selection (random within-household sampling). Panelists selected for an AmeriSpeak study earlier in the business week are not eligible for sample selection until the following business week.


In this study, surveying will be conducted with a mixed-mode approach of both online and telephone interviews. NORC has estimated that approximately 17% of a general population survey using its panel are completed via phone, and the rest are expected to be online. Online surveying necessitates an invitation email, which will be delivered to respondents in the panel. A template for the invitation from NORC is found in Attachment 7 and includes programming language for including the panelist’s name and the specific point incentive for this study.


The AmeriSpeak Panel is a probability-based panel representative of the total US population. Since the panel is not a simple random sample, a design effect reflects the multi-stage panel recruitment design, which includes subsampling of initial non-respondents for the face-to-face, in person recruitment in the non-response follow-up stage. The design effect for this study is expected to be approximately 1.75. Including the design effect, the margin of error for a 50% statistic at the 95% confidence level would be +/- 4.1 percentage points. For example, on a Yes/No question where 50% of the respondents answer “Yes,” we have 95% confidence that the population measurement is between 45.9% and 54.1% (taking into account sampling error). The sampling margin of error decreases for survey statistics below or greater than 50%. Therefore, the sampling margin of error estimate of +/-4.1 percentage points is a conservative estimate of the margin of error.


This relatively high degree of precision is needed in this survey because, as described in the justification in Supporting Statement A, part of the objective is to understand the composition and size of different audience segments who know or support Feed the Future’s mission to varying degrees. To do so, this survey’s sample must be representative. But because the sample is nationally-representative, there are no expected unusual problems requiring specialized sampling procedures in this research. There will be no periodic data collection cycles to reduce burden since this is a one-time survey.


  1. Methods to Maximize Response Rates and Deal with No Response


Participants in this study are registered with AmeriSpeak and will be offered survey choice “points” to redeem for prizes which are commonly provided to survey panel respondents who complete online surveys. The points will not be sent to respondents from USAID, but instead will be provided by the online panel provider to respondents who complete the survey. This is part of the business model of the online panel provider.


All panel-based research organizations, whether probability-based such as AmeriSpeak or non-probability, motivate panel members to continue participating in the surveys through an internal rewards program. Relatively small amounts of points are used for AmeriSpeak panel surveys based on an understanding of what would keep the participants engaged and motivated to obtain maximum retention of panelists and survey participation. For this particular study, points worth $6 will be awarded to panelists for completing the survey.


Panelists who do not respond to the initial survey invitation will receive up to two reminders emphasizing the importance of their participation in the project (included in Attachment 7). Telephone panelists will receive multiple follow-up call attempts at strategic times over the course of the survey recruitment period.


NORC will calculate and report unit and item non-response rates and carry out a non-response bias analysis following the guidelines in Standard 3.2 of the OMB Standards and Guidelines for Statistical Surveys. NORC will assess and measure non-response bias by evaluating the demographic and geographic representativeness of the survey participants compared to the Current Population Survey (CPS) population benchmarks.


  1. Tests of Procedures or Methods to Be Undertaken


The survey will be tested and reviewed thoroughly both before and after initial deployment. After the survey is programmed, the NORC programming team will conduct quality control reviews to ensure the work is error-free; then, KRC Research will review the study again for quality and accuracy. In its testing, KRC Research tests for missing survey components, incorrect or missing survey or question routing logic, inaccuracy in conveying initial instructions for programming, misspellings, poor formatting, language or content that may be confusing when displayed on the screen for online survey takers, and phrasing that may be unclear or convoluted for phone survey takers.


After testing has been completed and any corrections or revisions made, NORC will deploy the survey to a subset of the total sample size before suspending the survey progress to allow for KRC Research to check the raw data files. This pause after “soft launch” typically occurs at 10% of survey completes. At this point, KRC Research will review the raw data question by question to ensure programming and logic is displaying correct questions to correct audiences (where applicable), all questions have proper base sizes, and there are no highly unusual initial findings to suggest that a question needs rephrasing or clarification. Once this soft launch review has been completed, KRC Research will authorize deployment of the survey to the remaining sample.
