Reddit social dimensions

Accompanying dataset for paper "Multidimensional Tie Strength and Economic Development" reddit_messages_dimensions: author: reddit users who sent the message time: timestamp of message dest_author: recipient of message author_state_code: estimated state of residence for the sender dest_state_code: estimated state of residence for the receiver {dimension}_binary_adaptive_{threshold}: binary score that indicates whether the message expresses the given dimension when filtering messages according to the specified threshold regression_file: state_code: the 2-letter code of the state state: name of the state lat_centroid: latitude of the state centroid lon_centroid: longitude of the state centroid population_2010: resident population in 2010 population_2015: resident population in 2019 population_2019: resident population in 2019 gdp_per_capita_2017: GDP per capita in year 2017 user_count: number of reddit users in the dataset {spatial|social}_diversity_{dimension}_{threshold}: measure of spatial|social diversity calculated for a given social dimension, using the specified threshold on the dimension scores capital: capital of the state diversity_{social|spatial}_all_minstrength_{n}: measure of spatial|social diversity calculated using all social links and a minimum threshold on n messages sent
