Atlantic demographic parameters, 2013

Numerous text files with demographic parameters, for use in \"Atlantic-region\" simulation of African population and migration, in which the enslaved are dominantly male. Files are by sex and age group, giving specific parameters for 2x17 matrices. An introductory text file (\"Introduction to Atlantic parameters\") gives details on file names and definitions of the various age groups. Files are for population size \"p\"; for rates of fertility \"f,\" survival \"s,\" capture \"c\"; and for the partition coefficient \"pc,\" the proportion of captives retained in the land of capture.本数据集包含多份载有人口统计参数的文本文件，用于大西洋区域（Atlantic-region）的非洲人口与迁徙模拟研究，该研究场景中被奴役者以男性为主体。文件按性别与年龄组划分，为2×17矩阵提供专属参数。另有一份名为"Introduction to Atlantic parameters"的说明文本文件，详细说明了各文件的命名规则以及各类年龄组的定义。涵盖的参数包括：人口规模参数`p`、生育率`f`、存活率`s`、被俘率`c`，以及分区系数`pc`（即被俘者被留存于俘获地的比例）。
