  We present Coronavirus disease 2019 (COVID-19) statistics in China dataset:
daily statistics of the COVID-19 outbreak in China at the city/county level.
For each city/country, we include the six most important numbers for epidemic
research: daily new infections, accumulated infections, daily new recoveries,
accumulated recoveries, daily new deaths, and accumulated deaths. We cross
validate the dataset and the estimate error rate is about 0.04%. We then give
several examples to show how to trace the spreading in particular cities or
provinces, and also contrast the development of COVID-19 in all cities in China
at the early, middle and late stages. We hope this dataset can help researchers
around the world better understand the spreading dynamics of COVID-19 at a
regional level, to inform intervention and mitigation strategies for
policymakers.
