79 Urban population annual growth rate
Unit: %
Concept
Annual average increment of urban population growth
Comments It is calculated by the expression: i = n the root of [p ( t + n) / p (t)] - 1
In which P (t + n) and P (t) are urban population corresponding to two successive
dates ( n e n + t), and n is interval of time between these dates, measured in year
and fraction of year.

Observations
81 Half Year Population in municipalities with population over 750.000 inhabitants
Unit:
Total in absolute terms
Concept
Half-year estimate of resident population in municipalities with population over
750.000 inhabitants.
Comments
Estimates were obtained by the application of the demographic growth tendency
method that has as main principle the subdivision of a bigger area, in which the
estimate is known, in “ n “ smaller areas. Emphasising that municipalities were
considered the smaller areas in relation to the corresponding Federation units.

Observations
In 1996 there was no calculus for estimate population, as the Population Count
was undertaken.
