  • UnstableUse caution in interpreting, the estimate has a relative standard error greater than 0.30 and may not be reliable.
  • StableA count or rate is considered "Stable" when the relative standard error (RSE) is below 0.30 and a minimum of 30 respondents answered the question.

Data Notes

  • Question Wording:

    Based on a series of questions and the baby's age at the time the questionnaire was completed. Did you ever breastfeed or pump breast milk to feed your new baby after delivery, even for a short period of time? Are you currently breastfeeding or feeding pumped milk to your new baby? How old was your new baby the first time he or she ate food (such as baby cereal, baby food, or any other food)? How old was your new baby the first time he or she drank liquids other than breast milk (such as formula, water, juice, tea, or cow's milk)?
  • Weighted Survey Data

    The percentages reported above have been produced by weighting the sample so that the results better represent the population of Hawaiʻi. Numerator and denominator data have been rounded to the nearest 100. In cases where the numerator is 49 or less, it is displayed as 50.

Data Issue

Statistical Stability

Relative standard error, or RSE, is the standard error expressed as a proportion of the point estimate.

"Stable" is displayed when the RSE is below 0.30.

"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 decision making.

Problems with statistical instability typically occur when there is a small number of health events in a small population. You may combine years or otherwise increase the population size used in the query to achieve a more stable count or rate.

Survey Sample

PRAMS uses a two-stage, stratified random sampling method to identify the sample. The sampling frame is drawn from birth certificates. Each month, approximately 200 women who are 2 to 4 months post-delivery are chosen. The sample includes only residents of Hawai'i who had a recent live birth in the state. The results are weighted to ensure accurate representation of the population.
