population census
important source of health information
Population Census
carried out to assess the national needs and plan programs for the people’s welfare

usually done on a full moon night
De Facto Method of Census
not time consuming
done within one night
De Facto Method of Census
households are actually present in their places of residence
De Facto Method of Census
Even persons present at other places within the country are enumerated
De Facto Method of Census
Persons who are travelling during the night in trains, buses
and aeroplanes cannot be enumerated
De Facto Method of Census
time period for enumeration is fixed for only one night, it requires large number of trained enumerators
De Facto Method of Census
data are to be collected within a short period of one night, the census work may not be completed
staff may fill up the gaps of their own based on guess
De Facto Method of Census
households may not provide accurate information to the enumerators who are unwelcome at add hours
De Facto Method of Census
enumeration period of two or three weeks is fixed
De Jure Method of Census
enumerators collect information from households by visiting them multiple times
De Jure Method of Census
Persons residing temporarily at a place are not enumerated
Only persons residing permanently at a place are counted in it
De Jure Method of Census
called real method
the enumerators are given sufficient time to collect information
De Jure Method of Census
diverse data are used by the Census Commission in arriving at various aspects of population growth
De Jure Method of Census
data are further used by administrators for policy formulations regarding health and family planning, poverty alleviation
Academic people use them for research work
De Jure Method of Census
Persons who are not residing permanently at a place at the
time of enumeration are usually left out
De Jure Method of Censuses
problem arises when a person has two houses at two different towns and resides in them for the purpose of business
De Jure Method of Census
During the period of census, if the enumerator has filled up the census schedule of a particular household on a specific date and a birth or death takes place there, this will not be accounted for in the census
De Jure Method of Census
degree to which the results of a study are correct for the sample of the patients being studied
Internal validity
applies to the conditions of the particular groups of patients being observed and not necessary to others
Internal validity
degree to which results of an observation hold true in other settings
External validity (Generalizability)
assuming that patient in a study are comparable with other patients
External validity (Generalizability)
degree to which the results of a test correlates well with the results obtained from a related test that has already been validated
Concurrent validity
two tests are taken at the same time, and they provide a correlation between events that are on the same temporal plane (present)
Concurrent validity
degree to which the results of a test correlate to the results of a related test that is going to be done sometime in the future
Predictive validity
difference of the time period between the administering of the two tests allows the correlation to possess a
Predictive validity
extent to which the results can be reproduced when the research is repeated under the same conditions
Reliability
assessed by checking the consistency of results across time, across different observers, and across parts of the test itself
Reliability
Whether consistently receives the same results when you repeat measurements over time
Test-retest reliability
Whether receives the same findings while conducting the same measurements with various raters or observers
Interrater reliability
accuracy of measurements itself: Do several test components that are intended to measure the same things get the same results
Internal consistency reliability
Administer two different form of the same test to the same group of participants
Parallel form reliability
