The crude death-rate is 0-4 above that of 1935 and 0-7 above that of 1930, the lowest on record. The infant mortality is 2 above that of 1935, which was the lowest on record, and is the same as that of 1934, the previous lowest on record. In 122 county boroughs and great ...

The birth rate, however, is declining more slowly than the death rate. Birth rates in the state over the period for the overall population, rural areas, and urban centers are more than twice as large as the death rates in any given year, one of the main reasons for population growth in...
The lack of balance between birth and death rates is particularly known in many developing countries. This phenomenon occurs when a large percentage of a country's population is of childbearing age. Even if the birth rate of people in developing countries reaches replacement level, that is, if ...

Deaths also outnumbered births for the first time last year. China logged its highest death rate since 1976 - 7.37 deaths per 1,000 people, up from 7.18 the previous year. 去年死亡人数首次超过新生人数。同时,死亡率也达到了自1976年以来新高:每千人死亡7.37,高于前一年的7.18。
Vital rates, relative frequencies of vital occurrences that affect changes in the size and composition of a population. When calculated per 1,000 inhabitants—as is conventional in vital-statistics publications—they are referred to as crude rates. More
The dynamics of fractional population sizes yi=Yi/N in homogeneous compartment models with time-dependent total population N is analyzed. Assuming constant per capita birth and death rates, the vector field Y˙i=Vi(Y) naturally projects to a vector field
