Low Birth Weight

Birthweight is the first weight of the newborn obtained after birth. Low birthweight is defined as singleton, term births weighing less than 2,500 grams or 5 pounds 8 ounces. Term birth is defined here as the birth at or above 37 completed weeks of gestation.

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). The following conventions are used here to interpret the RSE. * 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 [].
