The size of the project as well as the differences
in birth rates and infant death rates
account for these variations in numbers of
deaths. For example, the Sherbrooke project
covered a large geographic area in the
Eastern Townships of Qu6bec Province in
Canada; since the birth rate was low and
likewise the infant death rate, tile number
of deaths was small. In contrast, the Recife
project (where there were 3,635 deaths)
was limited to three districts of the city
and the birth rate was nearly three times
that in Sherbrooke and the infant death
rate about five times higher. Thus, throughout
this report these variables must be
taken into account in interpreting the
results.
In addition to SAo Paulo, Bolivia, and
Recife, two other projects produced more
than 3,500 deaths: Monterrey with 3,953
and El Salvador with 3,820. In only two
projects were there less than 1,000 deaths:
Sherbrooke and California, which had the
lowest birth rates and infant death rates
and yet relatively large geographic areas.
For the California project data for only
one year were collected. In accordance with
tie approved plan, the projects in Ribeirfo
Prato, Cali, Cartagena, and Medellin were
relatively small, with the numbers of deaths
varying from 1,126 to 1,627.
Of the total of 35,095 deaths, 32,700 or
93.2 per cent were believed to have been
registered* and thus included in the official
statistics (Table 2). In the 13 Latin American
projects the percentages varied from
79.8 to 99.6, with five projects laving less
than 90 per cent registered. Each principal
collaborator uncovered deaths that had not
3,953 3,765 95.2 been registered; several introduced intensive
808 808 100.0 sieeacstofn
searches to find such suhIsigdah. missing deaths.
California project . . 1In Sherbrooke 94.3 per cent of deaths were
registered, and in California death certificates
were the only source of information
used since a search for unregistered deaths
was considered unnecessary. The present
report includes all deaths that were known,
both registered and unregistered.
To illustrate the registration problem,
Table 3 provides the detail by age at death.
The situation was particularly serious for
infant mortality (Figure 17). In six projects
10 per cent or more of infant deaths
were not registered. Within the neonatal
period (Figure 18), deaths in the first day
of life were the most seriously affected,
with those unregistered reaching 10 per cent
or more in 10 projects. Of the deaths
within 1-27 days, registration was lacking
for 10 per cent or more in five projects.
* In La Paz and San Salvador, death certificates
were prepared in the hospitals and for some there
was no evidence regarding registration. Whenever
there was doubt, it was assumed that the death had
been registered.
