The totalfertility rate is then obtained. Totalfertility rate was 5.51 children born per woman. It is unlikely that this heralds a decline in the totalfertility of these cohorts. A multiple regression analysis was carried out of totalfertility rate on relevant independent variables. At present (1972) women aged 30-49 still account for 30 % of totalfertility. The analyses are based principally on totalfertility rates by occupation. The totalfertility rate has continued to go down, and reached 1.25 in 2005. This showed a very low zero order correlation coefficient with totalfertility rate, and was not considered worth including. The totalfertility rate is the average number of live births per woman aged between 15 and 49. The totalfertility rate was four children per woman and the crude birth rate was 32 per 1,000. The totalfertility rate is lower in small countries, where we use small to denote land area rather than population. As stated at the beginning, the totalfertility rate became lower than the previous record in 1989. Totalfertility of 0.23% in triploid males indicated high sterility when compared with that in the diploid control (97.75%). For example, why was the observed totalfertility rate about 5 or 6 rather than 2 or 3? Marital fertility rates refer to fertility among currently married women, and fertility among the entire population is better indicated by the totalfertility rate. Between 1947 and 1957, totalfertility rates fell by more than half - the first such experience in the history of mankind. For example, in the discussion of fertility decline and demographic transition, the totalfertility rate or the average number of births have been widely used. The totalfertility rate is lower in island nations than non-island nations, and in small land-area nations than large land-area nations. The totalfertility rate is then obtained by summing the age-specific fertility rates at each age from 15 to 45 (or 49). To establish whether these trends reflect actual changes in fertility, the totalfertility rate and the gross and net reproduction rates are examined. The total population is 3-8 million, the crude birth rate is 47-5 per 1000 and the totalfertility rate is 6-1. Further insight into these changes may be gained by studying the changes in agespecific, age-marital-specific, general and totalfertility rates. Since extramarital births up until 1945 were less than 5% of the total births, the effect on totalfertility is negligible. It is not known how the totalfertility of cohorts marrying before 1936 compares with that of cohorts marrying after 1936. These examples are from corpora and from sources on the web.
