: Total number of years of the newborns in the Life table
who will continue to live;
l

: Number of persons who live to the age of 0 of the Life table
(the set of original newborns is observed).
Life expectancy at birth is one of the integrated indicators calculated from the Life
table.
The Life table is a statistical table that includes the indicators showing the viability
of population moving from one age to the next and the mortality of the population at
different ages. The Life table shows that from an initial set of the births (on the same
cohort), there will be how many persons who will live to 1 year, 2 years, ..., 100
years, ...; among them, there are how many persons at each of the certain ages who
will be dead before the following age; those persons who have reached a certain age
will have what probability of survival and death; how long is the life expectancy in
the future.
Rate of literate population aged 15 years and over
reflects the ability of
reading and writing of the population, serves to assess the development level of a
country, region or locality.
This indicator is calculated as the rate between the number of persons aged 15
years and over at time (t) who are literate (able to read, write and understand a
simple sentence in the national language, ethnic or foreign language) and the total
population aged 15 years and over at that time.

Singulate mean age at marriage
(SMAM) reflects the average number of
single life years of a presumptive cohort that has been lived single life before
getting married for the first time, with the assumption that this cohort’s proportion
of single by age is the same as the one collected at the intercensal time point.
LABOUR FORCE AND EMPLOYMENT

includes the employed persons aged 15 years and over
