Data have been directly age-adjusted to the U.S. 2000 standard population. Note: Age-adjusted rates and percentages are used to compare two or more areas or time periods and must not be used to estimate the number of persons affected. Please use crude rates and percentages to estimate the number of persons in the population.

Survey Sample
The New Jersey Behavioral Risk Factor Survey is a survey of non-institutionalized New Jersey adults aged 18 and over conducted using scientific telephone survey methods. Excluded are adults living in group quarters such as college dormitories, nursing homes, military barracks, and prisons. (Individuals who cannot conduct the interview in English or Spanish have also been excluded from the survey since it began in 1991, and cell phone interviewing did not begin until 2011.) Statistical Reliability
The margin of error (MOE) is calculated as the standard error of the estimate multiplied by 1.96. A MOE of 3 percentage points or less is commonly used as a standard of reliability for opinion surveys, although the reliability of a measure should ideally be assessed in conjunction with the specific use to which it will be put.

The relative standard error (RSE) also provides a measure of reliability for statistical estimates. The RSE is computed by dividing the standard error of the estimate by the estimate itself (or its complement, if the estimate itself is a proportion greater than 0.5) and multiplying by 100 to convert it to a percentage. (Estimates with a RSE above 25%-30% are commonly flagged as "unreliable" for government surveys, although the reliability of a measure should ideally be assessed in conjunction with the specific use to which it will be put.) 2018 Data
The NJBRFS query module contains incomplete data for 2018; data for the NJBRFS project were collected from January to March and October to November only and by two different survey companies. Additionally, supplemental data were received from other state BRFSS programs which conducted interviews throughout the year among New Jersey residents as part of a reciprocity agreement. Although the data meet minimum requirements to be included in the national BRFSS public-use data set, please consider the differences in collection when comparing estimates across years.
