Full survey documentation is available here.
When selecting more than one component from the same geographical level, Social Explorer provides a total for these components in the "All Selected Geographies" column. This total is for the available geographies only within the same geographical level. When a value is missing from one or more components from the same geographical level, Social Explorer denotes it with an asterisk (*) in the All Selected Geographies column.
Missing estimates can be caused by data suppression through various methods or restrictions that are applied to ACS data to limit the disclosure of information about individual respondents and to reduce estimates with unacceptable statistical reliability.
Filtering rules, based on statistical reliability of the ACS 1-year estimates, are used to ensure that Detailed Tables are not released where the majority of the estimates in the Detailed Tables have an unacceptable level of reliability.
Learn More about missing estimates and filtering rules in the data suppression document available on the ACS website at http://www.census.gov/programs-surveys/acs/technical-documentation/data-suppression.html.
