YRBSS Frequently Asked Questions

YRBSS data are not available by zip code, census tract, or school. Sample size limitations and confidentiality requirements do not support analyses at these levels.

YRBSS data are available for a small number of specifically funded local school districts or counties. CDC funds certain local school districts to conduct the YRBSS. Some of those local school districts are county-based. See Participation History & Data Quality for more information about county-based local school districts with YRBSS data. Data are only available for local school districts or counties on the list; no other local YRBSS data are available.

County-level identifiers are not available in the National YRBS data set or in most state data sets.

Most YRBS’s are conducted during the spring of odd-numbered years and results are released in the summer of the following year. Therefore, results from the 2017 national, state, and local YRBSS administration, for instance, were released in an MMWR Surveillance Summary during the summer of 2018. The specific release date for a given cycle is posted on the YRBSS home page as soon as it has been determined.

YRBSS questionnaires should be cited as follows:

Centers for Disease Control and Prevention. [survey year] Youth Risk Behavior Survey Questionnaire. Available at: www.cdc.gov/yrbs. Accessed on [date].

YRBSS data in a publication should be cited as follows:

The YRBSS questionnaires are in the public domain and no permission is required to use them. You may download and use the questionnaires as is or with changes at no charge. See YRBSS Questionnaires for the most recent YRBSS questionnaires.

YRBSS questionnaires are not available in languages other than English. YRBSS questionnaires were designed to be administered in a school setting. Therefore, it is important to consider the language used in regular classrooms. If testing in subjects such as math or social studies is conducted in English, it may not be necessary to translate YRBSS questionnaires. Check with school officials before deciding whether or not translation is needed.

YRBSS questionnaires are in the public domain, however, and may be freely translated and used in any language. No specific permission is required.

YRBSS data are not available by zip code, census tract, or school.  Sample size limitations and confidentiality requirements do not support analyses at these levels.

YRBSS data are available for a small number of specifically funded local school districts or counties. CDC funds certain local school districts to conduct the YRBSS. Some of those local school districts are county-based. See Participation Maps & History for more information about county-based local school districts with YRBSS data. Data are only available for local school districts or counties on the list; no other local YRBSS data are available.

County-level identifiers are not available in the National YRBS data set or in most state data sets.

YRBSS data sets are available for the United States overall, most states, some territories, some local school districts, and some tribal governments. Availability depends on YRBSS participation, data quality, and data-sharing policies. See Participation Maps & History for more information about data availability.

National YRBS data sets and documentation are available for download at YRBSS Data & Documentation. There is no charge for the data nor is permission needed to download or use the data.

Results are not available from every state for several reasons. First, four states (Minnesota, Oregon, Washington, and Wyoming) do not participate in the YRBSS. Second, some states that do participate do not achieve a high enough overall response rate to receive weighted results. Therefore, their results are not posted on the CDC web site and CDC does not distribute their data. The Participation Map and the Participation History & Data Quality tables provide more details on which states participated in the YRBSS and whether they obtained weighted data.

The National YRBS data sets posted on the YRBSS web site do not contain state or region identifiers because the national samples are not constructed to provide representative data at state or region levels. However, National YRBS data sets with state identifiers included are available upon request using the YRBSS Data Request Form. The National YRBS data sets will not contain data from every state because the National YRBS is an independent sample; it is not the aggregate of individual state and local data sets.

No, the National YRBS results are not the combination of state and local school district data. The National YRBS data are a separately drawn sample of high school students in grades 9-12 in the U.S. Some states may not have any schools chosen as part of the sample. States and local school districts each use a sample design that produces a representative sample of students in grades 9-12 for their state or local school district. If you want to analyze state or local school district data please see Participation Maps & History for more information about data availability.

No. The National YRBS sample is designed to be representative of students in grades 9-12 in the United States overall but does necessarily include students from every state.

National YRBS data sets are available in two file formats: Access and ASCII. Additionally, SAS and SPSS programs are provided to convert the ASCII data into SAS and SPSS datasets. They can be downloaded at YRBSS Data & Documentation.

State, local school district, territory, and tribal government data sets from surveys conducted since 1999 are available in SAS, SPSS, ASCII, and Access formats. State, local school district, territory, and tribal government data sets from surveys conducted prior to 1999 are available in ASCII only.

The YRBSS questionnaires are in the public domain and no permission is required to use them. You may download the questionnaires at no charge. See YRBSS Questionnaires for the most recent YRBSS questionnaires.

See A Guide to Conducting Your Own Youth Risk Behavior Survey pdf icon[PDF – 373K] for information useful to communities and groups that plan to conduct their own YRBS survey.

CDC provides data processing assistance only to states, territories, and local school districts that it funds directly to conduct a YRBSS. However, information on how the data are processed can be found on the Methods page and in the Methodology of the Youth Risk Behavior Surveillance Systempdf icon.

CDC has funding available for all 50 states and only a small number of territories, and large urban school districts during each five year funding cycle.

Before each YRBS cycle begins, CDC seeks input from subject matter experts (both inside and outside of CDC) regarding what questions should be changed, added, and deleted. This input is compiled for review by December of the odd-numbered year preceding the survey cycle (e.g., December 1, 2019 for the 2021 YRBS).

Proposed changes, additions, and deletions are then placed on a ballot, which is sent to the YRBS coordinators at all sites (states, territories, and local school districts). Each site votes for or against each proposed change, addition, and deletion. CDC considers the results of this balloting process when finalizing the standard questionnaire, which includes approximately 89 questions. A majority of sites must approve each change, addition, or deletion before it can be implemented.

For the national YRBS, approximately 10 questions are added to the standard questionnaire each cycle. These questions typically reflect emerging areas of interest for CDC and stakeholders.

Additional questions of interest are included on an Optional Question List, from which sites can select questions for their questionnaire. Final wording for questionnaires and the Optional Question List is based on the results of cognitive testing and input from subject matter experts.

All suggested additions and changes should be submitted using the YRBSS Question, Comment, and Data Request Form. These suggestions must be received by December 1 of the odd-numbered year preceding the survey cycle (e.g., December 1, 2019 for the 2021 YRBS). All suggestions are then compiled and reviewed by CDC before entering the ballot process described above.

There is no evidence that simply asking students about health behaviors will encourage them to try that behavior.

The YRBSS questionnaire should be cited as follows:

Centers for Disease Control and Prevention. [survey year] Youth Risk Behavior Survey. Available at: www.cdc.gov/YRBSS. Accessed on [date].

YRBSS data in a publication should be cited as follows:

The YRBSS assesses six categories of priority health behaviors—behaviors that contribute to unintentional injuries and violence; sexual behaviors related to unintended pregnancy and sexually transmitted diseases, including HIV infection; alcohol and other drug use; tobacco use; unhealthy dietary behaviors; and inadequate physical activity. In addition, the YRBSS assesses obesity, overweight, and other important health issues.

Yes. State and local agencies that conduct a YRBS can add or delete questions to meet their policy or programmatic needs. Specific guidance on the parameters that must be followed during questionnaire modification is provided to those agencies funded by CDC to conduct a YRBS.

Yes. All students in sampled classrooms are included as long as they are able to respond to the questionnaire in a private and anonymous matter.

CDC worked with partners and researchers for several cycles to develop a credible question to identify transgender students. A question recommended by CDC was successfully piloted by 11 states and 10 local school districts during the 2017 YRBS cycle. Cognitive interviews conducted in March of 2018 also indicated that the question functioned well. This question is now included in the YRBS Optional Question list for any interested site to use.

National, state, territory, tribal government, and local YRBS data come from separate scientific samples of schools and students. National YRBS data are not the aggregate of the state YRBS data sets. State, territory, tribal government, and local YRBS data are not subsets of the National YRBSS data set. National, state, territory, tribal government, and local YRBS’s all follow the same survey methodology and use the same core questionnaire.

No. However, middle school results are available for some states, districts, territories, and tribal governments that have elected to conduct a middle school YRBS in their jurisdiction. Middle school YRBS results are available on Youth Online.

No, the National YRBS was not designed to produce representative estimates at the state level.

This type of analysis has significant limitations and should be conducted with caution. A state-level characteristic, such as the presence of a state law, can be added to a regression model as an exogenous (independent) variable and will yield statistically correct estimates. However, it is important to fully consider the context of these estimates. The National YRBS was not designed to produce representative estimates at the state level, the number of students chosen from states varies considerably and is usually too small to generate precise or stable state-level estimates, and fewer than 50 states are included in the national sample each cycle. Thus, researchers should fully investigate the implications and interpretations of this type of analysis and should understand the sampling design of the National YRBS and how that design might influence their results. See Methodology of the Youth Risk Behavior Surveillance Systempdf icon for more information about the National YRBS sampling design.

No, the National YRBS was not designed to produce estimates by urban/rural status. In the National YRBS, PSUs are selected based on urban and non-urban definitions, but it does not necessarily follow that a non-urban area is rural. Urban status indicates only that the PSU was one of the largest 54 metropolitan statistical areas (MSAs); non-urban indicates that the PSU was not one of the largest 54 MSAs; it could be rural but is not necessarily rural. See Methodology of the Youth Risk Behavior Surveillance Systempdf icon  for more information about the National YRBS sampling design.

State, territorial, tribal government, and local agencies and nongovernmental organizations use YRBSS data to set and track progress toward meeting school health and health promotion program goals, support modification of school health curricula or other programs, support new legislation and policies that promote health, and seek funding and other support for new initiatives.

CDC and other federal agencies routinely use YRBSS data to assess trends in priority health behaviors among high school students, monitor progress toward achieving national health objectives, and evaluate the contribution of broad prevention efforts in schools and other settings toward helping the nation reduce health risk behaviors among youth.

Yes. The YRBSS tracks aggregate changes in student behavior over time. See the National Trends Fact Sheets for more information.

No. Each cycle a new sample of schools and students is drawn. Students who participated cannot be tracked because no identifying information is collected.

Although prevalence estimates generated for students in each racial/ethnic subgroup are representative of these students nationally, caution should be used when analyzing and interpreting these data. Because of the small numbers of students in some racial/ethnic subgroups who participate in any single National YRBS, the estimates may lack precision. Precision can be improved by combining multiple years of National YRBS data.

Research indicates data of this nature may be gathered as credibly from adolescents as from adults. Internal reliability checks help identify the small percentage of students who falsify their answers. To obtain truthful answers, students must perceive the survey as important and know procedures have been developed to protect their privacy and allow for anonymous participation.

The Methodology of the Youth Risk Behavior Surveillance Systempdf icon contains a description of most of the methodological studies conducted to date on the YRBSS questionnaires or YRBSS data collection procedures. In addition, the list of YRBSS MMWR publications and journal articles contains the actual journal articles describing the results of these studies.

These methodological studies include test-retest reliability studies on the 1991 and 1999 versions of the questionnaire; a study assessing the validity of self-reported height and weight; a study assessing the effect of changing the race/ethnicity question; a study examining how varying honesty appeals, question wording, and data-editing protocols affect prevalence estimates; and a study examining how varying the mode and setting of survey administration affects prevalence estimates.

See Methodology of the Youth Risk Behavior Surveillance System—2013pdf icon for details about how YRBSS are conducted.

For the national, state, territory, tribal government, and local YRBS samples, schools are selected with probability proportional to the size of student enrollment in grades 9-12 and then required classes of students (e.g., English classes) or a specific period of the school day (e.g., 2nd period) are randomly selected to participate. Within selected classes, all students are eligible to participate. See the Methodology of the Youth Risk Behavior Surveillance Systempdf icon for a more detailed description of sampling procedures.

National YRBS data are representative of all public and private school students in grades 9-12 in the 50 states and the District of Columbia. National YRBS data sets are not the aggregate of the state YRBS data sets; the National YRBS uses a separate scientific sample of schools and students.

Most state, territory, tribal government, and local YRBS data that are weighted are representative of all public school students in grades 9-12 in the respective jurisdiction. State, territory, tribal government, and local YRBS data that are not weighted are representative only of the students who completed the survey in the respective jurisdiction.

Weighting is a mathematical procedure that makes data representative of the population from which it was drawn. In the YRBSS, only surveys with a scientifically drawn sample, appropriate documentation, and no evidence of significant nonresponse bias are weighted.

YRBSS data are weighted to adjust for school and student nonresponse and to make the data representative of the population of students from which the sample was drawn. Generally, these adjustments are made by applying a weight based on student sex, grade, and race/ethnicity.
