Animarium
收藏资源简介:
Animarium是一个开放、可复现的意大利城市合成人口数据集,由博洛尼亚大学创建,基于ISTAT发布的人口普查与登记表、市政开放数据等公开聚合数据生成。该数据集涵盖11个意大利城市,包含1,814,317名个体与887,937个家庭,每个个体拥有最多九项人口统计属性(通过最大熵联合模型生成)、23项态度与健康变量(完整向量来自真实调查受访者)、精确到普查区段的年龄与地址,以及受家庭规模分布约束的家庭结构。创建过程采用确定性流水线,分为四个环:联合模型训练、整向量捐赠、空间分配与家庭组装,可在单台工作站上33分钟内完全复现。数据集旨在为城市模拟、人口统计研究及大语言模型驱动的仿真提供无隐私风险的合成人口基底,避免使用真实个人数据。
Animarium is an open, reproducible synthetic urban population dataset created by the University of Bologna, generated from publicly aggregated data including census and registration records published by ISTAT and municipal open data. This dataset covers 11 Italian cities, containing 1,814,317 individuals and 887,937 households. Each individual has up to nine demographic attributes (generated via a maximum entropy joint model), 23 attitudinal and health variables (complete vectors derived from real survey respondents), age and address precise down to the census tract level, and household structure constrained by household size distributions. The creation process adopts a deterministic pipeline divided into four cycles: joint model training, whole vector donation, spatial allocation, and household assembly, which can be fully reproduced on a single workstation within 33 minutes. This dataset aims to provide a privacy-preserving synthetic population base for urban simulation, demographic research, and large language model (LLM)-driven simulations, avoiding the use of real personal data.
