Why This Indicator Matters

Birthweight correlates with a child’s future development and health. Children born under 5.5 pounds have a higher probability of experiencing pre-and post-natal developmental problems, short- and long-term disabilities, and are a greater risk of dying within the first year of life.[i] Among the risk factors for low weight births, intrauterine exposure to tobacco has been cited as a key correlate for low birth weight, small gestational age, and preterm births.[ii] Increased income from the Earned Income Tax Credit (ETIC) has been shown to reduce the incidence of low birthweight births and increase mean birthweights among babies whose mothers received the credit.[iii] Studies suggest this is in part because increased income is linked to increased prenatal care and reduced negative health behaviors.[iv]

Definition and Source

PROVIDER

Definition

This indicator reports the number and percentages of babies born weighing fewer than 2500 grams, which is considered low birth weight.








Data Source

Connecticut Department of Public Health, Vital Statistics, 2009, 2010, 2011, 2012, 2013, 2014, and 2015, 2016, 2017, 2018, and 2019, Table 4.

Notes

Methodology: The total numbers and percentages of low birth weight births were obtained from State Department of Public Health Vital Statistics tables. Counts of five or fewer—excluding zero—were suppressed, as were percentages generated from suppressed totals. Denominators used for calculating percentages exclude records with missing data.

NA: Not Available
S: Data Suppressed

The data source has not published new data for this indicator in recent years, but the indicator will be updated on the KIDS COUNT Data Center if or when new data are released. Until then, these data may provide useful historical information for those working in this field.
