Library ANC.IND.9
WHO Antenatal Care (ANC) Indicator 9
Percentage of pregnant women whose baby’s heartbeat was listened to at least once during ANC 

Numerator: Number of pregnant women whose baby’s heartbeat was listened to  
Numerator Computation: COUNT of all women who had their baby’s heartbeat listened to at least once during pregnancy 
Denominator: Total number of pregnant women with a first contact
Denominator Computation: COUNT of all women whose records were closed (ANC close form) in the last reporting period due to any of the reasons below:
*live birth
*stillbirth
*miscarriage
*abortion
*woman died
*lost to follow-up
*moved away

Disaggregation:
Age (10-14, 15-19, 20+)
