Mark Elvin, Josephine Fox, Marriages, Births, and Deaths in the Lower Yangzi Valley during the Later Eighteenth Century
Article:
Figure 1. The ranges covered by the earliest and latest years of death, or the award of a banner, to a faithful widow or faithful fiancee in Qing times in the Lower Yangzi valley.
Figure 2. The status of the families of the husbands of virtuous women, and of their own families, in the Lower Yangzi valley in midQing times.
Figure 3. The conversion of Chinese sui years of age to exact western years of age and the determination of the density of sets of suiassigned point events, assumed equally distributed, over the year between two exact western years of age.
Figure 4. Proportions of females in the sample virilocating and marrying during a year of age, and of those evermarried by exact age.
Figure 5. Provisional Lower Yangzi valley male and female standard life tables, with logits for males, and q(x) for males. Note that the precise age of minimum male mortality is given by the program life.table as being 0.0038 at age 12. (The mortality is the probability of dying in the course of the year starting at the exact age indicated.) There are two different scales for the yaxis.
Figure 6. Female mortality, and expectancy of life from 5180 years, in the Lower Yangzi valley during the midQing: a comparison of the female standard life table with the data.
Figure 7. Data and model values for the differential survival of parentsinlaw using M/B.
Figure 8. Differences in age between married couples, showing the effects of transforming the original data template from Hengyang (mean + 3.347 years) to match the Lower Yangzi valley mean of 3.221 years. [now revised to 3.1719 years]
Figure 9. Female bereavements by age, with data values, expressed as proportions over the span of ages 15..28, versus model values expressed as component of female l(x). Note that the data value for the year following western age 28 is not fully covered by the sui data, which formally stop at the equivalent of 28.5 years, and is therefore approximated here as double this last value.
Figure 10. The agespecific probability that, given at least one surviving son, a widow has exactly 2 surviving sons. The data values have been adjusted by converting a proportion of the ambiguous cases (those showing 1 or more sons) to cases of exactly 2 surviving sons. The agespecific proportion converted is determined by the selection of the linear agegradient running from ages 12..30 that gives the best fit to the model. Here the size of the proportion increased rises from 0.0 to 0.28, so the percent altered by age 30 (not included) is 28. For comparison, an unadjusted data curve is also shown, together with the total numbers of all cases for each age, and of the corresponding numbers of 1+ (i.e. ambiguous) cases.
Figure 11. Agespecific birth rates for both sexes together, and for girls and boys separately, with the lifetable proportions of women reproducing at each age.
Figure 12. The rate of remarriage by age of Lower Yangzi valley widows, with the proportions by age of the birthcohort, and of the female agegroup, represented by nonremarried widows.
Figure 13. Female expectancies of life up to 85 at different ages in Jiaxing, Shangrao, and Shexian.
”@  Note: Readers of the above two articles will observe that in almost all cases the mean values of the basic measures determined by the counting programs on this site now differ by a very small amount from those given in the articles. This is because, since the texts of the articles were finalized, we have in effect added a small number of cases ( 300) to the lower Yangzi valley database, twothirds of them for Poyang. These differences make essentially no difference to the reconstruction presented in the articles. The extra data will be incorporated when we come to the further round of timeconsuming interlocking calculations needed for the next report on the progress of the project. ”@
