Decentralized district-based health planning is essential in India because of the large inter-district variations. Realizing the need for preparing a comprehensive district health profile on key parameters based on a community set up, the Annual Health Survey (AHS) has been designed to yield benchmarks of core vital and health indicators at the district level; prevalence of disabilities, injuries, acute and chronic illness and access to health care for identified morbidities; and access to maternal, child health and family planning services. By virtue of being a panel survey, AHS  enables better capturing of the health seeking behavior of the public as compared to other periodic cross-sectional surveys, and also helps to formulate right strategies. The objective of Annual Health Survey (AHS) is to monitor the performance and outcome of various health interventions of the Government including those under National Health Mission (NHM) at closer intervals through the benchmark indicators.

 The sample size at the district level has been derived taking Infant Mortality Rate as the decisive indicator and host of other practical issues related to execution of the survey. Keeping in view the mammoth size of the sample, it was a conscious decision of the Government to initially confine the survey to the 284 districts (as per 2001 Census) of the 8 Empowered Action Group States (Bihar, Jharkhand, Uttar Pradesh, Bihar, Madhya Pradesh, Chhattisgarh, Orissa and Rajasthan) and Assam for a three year period starting from 2010-11. These 9 high focus States with relatively high fertility and mortality account for about 48 percent of the total population in the country. During the Base line Survey in 2010-11, a total of 20.1 million population and 4.14 million households and during the first updation survey in 2012-13, 20.61 million population and 4.28 million households have actually been covered. The second updation survey (third and final round) covered a total of 20.94 million population and 4.32 million households in 2012-13. Despite being restricted to 9 States, the AHS is the largest demographic survey in the world and covers two and a half times that of the Sample Registration System.

The Second updation survey in all the nine AHS States was carried out with four Schedules. These are: (i) House-listing Schedule, (ii) Household Schedule, (iii) Woman Schedule and (iv) Mortality Schedule.

To supplement the information provided by Annual Health Survey (AHS), a biomarker component has been introduced in AHS to collect data on nutritional status, life style diseases like diabetes & hypertension and anemia in Empowered Action Group (EAG) States & Assam. This component, namely Clinical, Anthropometric and Bio-chemical (CAB) survey, is conducted in 2014 on a sub-sample of AHS in all EAG States namely Bihar, Chhattisgarh, Jharkhand, Madhya Pradesh, Odisha, Rajasthan, Uttarakhand & Uttar Pradesh and Assam.

  • In the House-listing Schedule, the mapping, listing and some key particulars like type and ownership details collected in the first updation survey in 2012-13 were updated for the existing houses and households and recorded afresh for the new houses and households in the second updation round.

For infant deaths, data related to symptoms preceding death is also provided. Mortality Schedule also includes information on various determinants of maternal mortality viz. case of deaths associated with pregnancy, information on factors leading/ contributing to death, symptoms preceding death, time between onset of complications and death, etc.
  • Clinical, Anthropometric and Bio-chemical (CAB) survey has collected information on nutritional status of women, children (1 month and above) and men, prevalence of anemia among women, children (6 month and above) and men, prevalence of hypertension and abnormal fasting blood glucose among women and men 18 years and above and utilization of iodized salt in households.   Stunting (Height for age), Wasting (Weight for height), Underweight (Weight for age) and under nourished (BMI for age) are the four major indicators available for measuring malnutrition level in children under 5 years. For children in the age 5 to18 years, under nourishment data is provided and for persons 18 years and above, data on BMI indicators (<18.5,≥25 and ≥30) is provided separately for male female and rural also. Information of Anemia, measured by Hemoglobin level, is available for sex wise children, women and men. For children, the data is available for age 6-59 months, 5-9 years, and 10-17 years.
