Query Results for American Community Survey - Family Households with a Single Female Head of Household as a Percentage of Total Households

Year Filter: 2013-2017 5-Yr ACS
Data Grouped By:NM Small Areas

Statistical Stability

Statistical stability, reported in the data table, is based on a statistic called the "Relative Standard Error," or RSE, which is the standard error expressed as a proportion of the point estimate (e.g., 30% of the point estimate).

A dash (-) means that the relative standard error (RSE) is below 0.30 and the count or rate may be considered stable.

"Unstable" is displayed when the RSE is 0.30-0.50. An unstable count or rate may fluctuate widely across time periods due to random variation (chance).

"Very Unstable" is displayed when the RSE is greater than 0.50. A very unstable count or rate should not be used to inform decisions. You may combine years or otherwise increase the population size used in the query to achieve a more stable count or rate.

Problems with statistical instability typically occur when there is a small number of health events in a small population. For more information on statistical stability, visit the NM-IBIS Reliability & Validity page [https://ibis.health.state.nm.us/resource/ReliabilityValidity.html].

American Community Survey Queries

The American Community Survey (ACS) is an ongoing survey conducted by the United States Bureau of the Census. It gathers data on demographic, economic and social characteristics at various geographic levels within the United States. Data from the ACS are aggregated into one, three and five year periods. The data presented in this query tool are aggregated at the five year level, which makes these estimates more stable for New Mexico's sparsely populated areas.

To improve the accuracy of the population count estimates in the data table, where feasible, the mid-year population estimates produced by the University of New Mexico Geospatial and Population Studies (GPS) Program have been used. For instance, the ACS percentage from the 2012-2016 dataset were applied to 2014 New Mexico GPS population estimates to provide an estimate for the number of New Mexicans affected. To see which person or household count estimates were used for this query, please see the data sources section.

The estimates for New Mexico's 108 Small Areas were calculated by aggregating the ACS data at the census tract level and pooling the standard errors.

New Mexico's 108 Small Areas

New Mexico Small Areas are 108 geographic areas across the state with population sizes that are just large enough to calculate rates for selected health events (e.g., diabetes deaths, asthma hospitalization, etc.). New Mexico small areas were based on population size, not land area. Most (95%) of the New Mexico small areas range in population size from 9,000 to 30,000 persons. Some counties have multiple small areas (Bernalillo County has 34 small areas within its boundaries). In other cases, entire counties (e.g., Harding, Quay and De Baca Counties) were combined to create a single small area.

Small Area median values were estimated as the median of the census tract medians for census tracts that comprise the small area.
