MobMeter: a global human mobility data set based on smartphone trajectories

This data set is supplement to this Scientific Reports article. The data set provides estimates of country-level daily mobility metrics (uncertainty included) for 17 countries from March 11, 2020 to present. Estimates are based on more than 3.8 million smartphone trajectories. Metrics: Estimated daily average travelled distance by people. Estimated percentage of people who did not move during the 24 hours of the day. Countries: Argentina (ARG), Chile (CHL), Colombia (COL), Costa Rica (CRI), Ecuador (ECU), Greece (GRC), Guatemala (GTM), Italy (ITA), Mexico (MEX), Nicaragua (NIC), Panama (PAN), Peru (PER), Philippines (PHL), Slovenia (SVN), Turkey (TUR), United States (USA) and Venezuela (VEN). Covered period: from March 11, 2020 to present. Temporal resolution: daily. Temporal smoothing: No smoothing. 7-day moving average. 14-day moving average. 21-day moving average. 28-day moving average. Uncertainty: 95% bootstrap confidence interval. Data ownership Anonymized data on smartphone trajectories are collected, owned and managed by Futura Innovation SRL. Smartphone trajectories are stored and analyzed on servers owned by Futura Innovation SRL and not shared with third parties, including the author of this repository and his organization (University of Bergamo). Contribution Ilaria Cremonesi of Futura Innovation SRL is the data owner and data manager. Francesco Finazzi of University of Bergamo developed the statistical methodology for the data analysis and the algorithms implemented on Futura Innovation SRL servers. Repository update CSV files of this repository are regularly produced by Futura Innovation SRL and published by the repository's author after validation.

本数据集为《科学报告》（Scientific Reports）学术论文的补充数据集。本数据集提供了17个国家自2020年3月11日起至今的国家级每日移动性指标估算值（含不确定性区间），估算基于超过380万条智能手机轨迹数据。

移动性指标包括：
1. 民众日均出行距离估算值
2. 当日24小时内未发生移动的人群占比估算值

涉及国家及对应国别代码：阿根廷（ARG）、智利（CHL）、哥伦比亚（COL）、哥斯达黎加（CRI）、厄瓜多尔（ECU）、希腊（GRC）、危地马拉（GTM）、意大利（ITA）、墨西哥（MEX）、尼加拉瓜（NIC）、巴拿马（PAN）、秘鲁（PER）、菲律宾（PHL）、斯洛文尼亚（SVN）、土耳其（TUR）、美国（USA）、委内瑞拉（VEN）。

覆盖时段：2020年3月11日起至今
时间分辨率：每日级
时间平滑方式：未平滑、7日移动平均、14日移动平均、21日移动平均、28日移动平均
不确定性表征：采用95%自助法（bootstrap）置信区间
