Predictions from Time Series Analysis of the Oscillations in Parish Register Series
Journal of Theoretical Biology, 1994Co-Authors: Stephen R. Duncan, Susan Scott, Christopher J. DuncanAbstract:Abstract Parish registers provide invaluable data series for theoretical population biologists and historical demographers alike and previous studies with time-series analysis have shown how the population dynamics of these communities can be determined and modelled. However, many demographic parameters of the community have previously been determined only by the laborious technique of Family Reconstitution. It is suggested that some of these functions may be estimated by the application of conventional time-series analysis to the aggregative annual totals in the registers of baptisms, marriages and deaths: (i) age of mother at birth of median child; (ii) estimations of fertility function; (iii) mean age at marriage; (iv) estimations of mortality function; (v) factors governing the population boom; (vi) the patterns of population dynamics that might be found and the detection of steady-state conditions in communities in England in the sixteenth and seventeenth centuries. These theoretical predictions have been verified in a parish where the demographic parameters have been determined by Family Reconstitution and excellent correspondence has been found.

explaining the rise in marital fertility in england in the long eighteenth century
The Economic History Review, 1998Co-Authors: E. A. WrigleyAbstract:T he two most effective ways of converting parish register data into estimates of fertility, mortality, and nuptiality in the past are generalized inverse projection and Family Reconstitution. In general, they produce reassuringly similar results for England in the early modem period.2 An earlier version of inverse projection, using aggregative tabulations from 404 parishes, was employed to generate the demographic estimates presented in the Population history of England, while, 16 years later, data from 26 parish Reconstitutions formed the basis for the findings published in English population history from Family Reconstitution.3 The far more refined measures produced by Family Reconstitution have enabled some of the input parameters used in inverse projection to be specified more accurately, and this in turn has led to minor modifications in the results obtained by inverse projection, but, whether the original or the modified parameters are used, comparison of the output from Reconstitution and inverse projection suggests that the two methods yield the '4 same 'big picture' Nevertheless, the later Reconstitution study has brought to light many previously unknown or obscure features of English population history, some of which are simultaneously illuminating and puzzling: illuminating because they enforce a revision of the received wisdom; puzzling because, although the existence of an unexpected pattern can be demonstrated, its explanation is unclear. This article explores a possible explanation of one of these new findings, the rise in marital fertility which took place during the eighteenth century, for which no satisfactory explanation was offered in English population history from Family Reconstitution.

How reliable is our knowledge of the demographic characteristics of the English population in the early modern period
The Historical Journal, 1997Co-Authors: E. A. WrigleyAbstract:Anglican parish registers have been the basis for most studies of population trends and characteristics in early modern England and one of the most important of the techniques used in analysing them has been Family Reconstitution.... This article attempts to describe the range of difficulties and dilemmas involved in studying the demography of populations in the past when using this source of data and this technique of analysis. A variety of tests is deployed to establish the degree of reliability attaching to the results obtained in a recent exercise based on the Family Reconstitution of 26 parishes and more generally to assess the opportunities open to scholarship in this area and the pitfalls associated with such work.

the effect of migration on the estimation of marriage age in Family Reconstitution studies
Population Studies-a Journal of Demography, 1994Co-Authors: E. A. WrigleyAbstract:Ruggles has shown that, if marriage and migration are independent phenomena, age at marriage estimates derived from Family Reconstitution studies can be misleading because those who marry late are more likely to have migrated before marriage than those who marry early. Marriage age estimates based on ‘stayers’ will therefore be lower than would be the case if ‘leavers’ were also included. Whether this was true of English Reconstitution data, however, is an empirical rather than a logical question. Evidence from the Census of 1851 suggests that the mean age at marriage of ‘leavers’ was very similar to that of ‘stayers’ (i.e. that marriage and migration were not independent phenomena). But, though age at marriage was much the same in the two groups, the proportions ever marrying were very different: celibacy was far commoner among ‘stayers’ than among ‘leavers’.

Family dissolution, Family Reconstitution, and children’s educational careers: Recent evidence for Sweden
Demography, 1997Co-Authors: Jan O. Jonsson, Michael GählerAbstract:Both longitudinal and cross-sectional analyses on a large and recent Swedish data set demonstrate that, compared to children in intact families, children who have experienced Family dissolution or Reconstitution show lower educational attainment at age 16. Time constraints do not seem to be an important mechanism behind the negative effect of separation. Economic deprivation affects children s attainment negatively, but downward social mobility appears to be an even more important causal mechanism: Losing the parent with the higher social position probably reduces social capital and aspirations. When we control for socioeconomic characteristics, a small net effect of separation and Reconstitution remains.
