Overview
Abstract
The AHDSS database contains the data resulting from the exhaustive coverage of demographic events within a geographically defined population, namely the Agincourt sub-district of the Bushbuckridge district of South Africa. As of May 2013, the study site consists of 30 research villages with a population of 107,500 people, living in 19,500 households.Units of Analysis
A range of tables store information in the database and are linked together to form the relational structure. The following tables exist:The Observations table records the details of each household interview. Examples of data fields: 'date of observation' and 'name of fieldworker'
The Individuals table records the basic information about each individual in the population. Examples of data fields: 'Name', 'Surname', 'Date of Birth' , 'Gender', 'Nationality', and 'Refugee Status'
The Residences table records the episode of an individual in a location. The key data are the date at which a residence starts or ends, and the event that starts an episode (e.g. birth, in-migration, or present at the start of the DSS), and/or the event that ends the episode (e.g. death, out-migration). If an episode has not ended and is still open, then it is marked as 'current'.
The Locations table records the dwelling place at which an individual is located. The residence episode records when a person enters or leaves this place. A location is a physical structure that has a corresponding latitude and longitude.
The Memberships table records the episode of an individual joining or leaving a household. The key data are the date at which a membership starts or ends, and the event that starts an episode (e.g. birth, in-migration, or present at the start of the DSS), and/or the event that ends the episode (e.g. death, out-migration). If an episode has not ended and is still open, then it is marked as 'current'. Included in this table is the relationship of the individual to the household head (e.g. wife, son, etc.) If a household head dies or out-migrates then the membership episode is closed and a new membership episode is opened containing the new relationship to household head.
The Households table records the social unit (i.e., household) of which an individual is a member.
The Union Episodes records the episode of an inidividual in a union another individual. This table records the date when a union starts, the event that started it (e.g., marriage, re-marriage), the date when a union ends, and the event that ends it (e.g., divorce, separation or death). The Union Episodes table links to the Marriage Attributes table which records details about marriages and informal unions.
There are several 'Event' tables, which record the details of the demographic events which bring an individual into the database or remove an individual from the database. A few key variables are recorded on each event of which a very important one is the date of the event. These tables include:
Pregnancies
Births
In-Migrations
Out-Migrations
A number of status observation tables are also stored in the database. These table record attributes of either individuals or households and are recorded as cross-sectional data at the time of a census. Most status observations are repeated over time. Other related tables include the Verbal Autopsy table which records information used to determine cause of death and the Maternity Historytable which records the details of a woman's fertility outside the study site and observation period.
At household level, such tables include:
Asset Status
Child Care Grants
Food Security Status
At the individual level, such tables include:
Adult Health Status
Child Care Grants
Child Morbidity
Cough Status
Education Status
ElderHealthCare
Fatherhoods
Father Support Status
Health Care Utilisation
IndividualGrantStatus
Labour Status
Stroke Status
Temporary Migrations
Vital Documents

Geographic Coverage
This database is a 10% sample of the full Agincourt database i.e. 10% of all "locations" in the demographic surveillance area. The current version available is extracted from cleaned database snapshot produced at the end of the 2011 AHDSS census round. This can be used as an evaluation tool for developing data requests and for familiarising the would-be analyst with the structure and availability of data in the Agincourt database. It also can be used as a teaching tool for demographic methods and the management of the demographic surveillance system data. It does not contain data that can be analysed for publication.Universe
The AHDSS database contains the data resulting from the exhaustive coverage of demographic events within a geographically defined population, namely the Agincourt sub-district of the Bushbuckridge district of South Africa. As of May 2013, the study site consists of 30 research villages with a population of 107,500 people, living in 19,500 households. (Note: this excludes the new villages added in 2013, which data will only be added to the data set in 2014). The population includes all persons resident in the study site thus requiring no sampling. The population includes people linked as temporary migrants to the households in the sub-district.Producers and Sponsors
