The perinatal mortality rate (PMR) differs from most other mortality rates used in community medicine because its denominator includes:

• A Live births only
• B Mid-year population of women aged 15 to 49 years
• C All pregnancies regardless of outcome
• D Total births, that is live births plus stillbirths ✓

Explanation

The perinatal mortality rate is defined as the number of stillbirths plus early neonatal deaths (deaths within the first 7 days of life) per 1000 total births, where total births means live births plus stillbirths. This is unique among common child mortality indicators, since IMR, NMR and U5MR all use live births as the denominator. Stillbirths are excluded from those denominators because they are not live born.
