Replication data for: A global perspective on social stratification in science
<p><strong>Replication materials for "A global perspective on social stratification in science"</strong></p> <p>This data comprises the number of Scopus authors by OECD macro field of science, country, authors' inferred gender, author's academic age, and bibliometric class. The sum of the column counts is: 8,225,368. </p> <p>**Please note**: there are 554 rows in the table indicated with "NA" where some of these variables are missing.</p> <p><strong>Paper metadata</strong><br>**Title**: A global perspective on social stratification in science</p> <p>**Authors**: Aliakbar Akbaritabara (Max Planck Institute for Demographic Research, Rostock, Germany), Andres F. Castro Torres (Max Planck Institute for Demographic Research, Rostock, Germany; Center for Demographic Studies, Barcelona, Spain), Vincent Larivière (Université de Montréal, Montréal, Canada)</p> <p>**Corresponding author and email**: Aliakbar Akbaritabar, akbaritabar@demogr.mpg.de</p> <p>**Abstract**: <br>To study stratification among scientists, we reconstruct the career-long trajectories of 8.2 million scientists worldwide using 12 bibliometric measures of productivity, geographical mobility, collaboration, and research impact. While most previous studies examined these variables in isolation, we study their relationships using Multiple Correspondence and Cluster Analysis. We group authors according to their bibliometric performance and academic age across six macro fields of science, and analyze co-authorship networks and detect collaboration communities of different sizes. We found a stratified structure in terms of academic age and bibliometric classes, with a small top class and large middle and bottom classes in all collaboration communities. Results are robust to community detection algorithms used and do not depend on authors’ gender. These results imply that increased productivity, impact, and collaboration are driven by a relatively small group that accounts for a large share of academic outputs, i.e., the top class. Mobility indicators are the only exception with bottom classes contributing similar or larger shares. We also show that those at the top succeed by collaborating with various authors from other classes and age groups. Nevertheless, they are benefiting disproportionately from these collaborations which may have implications for persisting stratification in academia.</p> <p>**Keywords**:<br>bibliometric data; research productivity; scientific collaboration; scientific mobility; scholarly impact and citations<br><br></p> <p><strong>Description of the data</strong><br>The dataset contains SIX columns as follows:</p> <p>**base_oecd**: Six OECD macro fields of science such as "Agricultural_Sciences", "Engineering_and_Technology", "Humanities", "Medical_and_Health_Sciences", "Natural_Sciences", "Social_Sciences", and "NA" (for missing) </p> <p>**base_countr**: Country name (see details in the paper)</p> <p>**gender**: Inferred gender based on the name of the author; it includes "fem" for "female", "mal" for "male", and "unkn" for "uknown" gender who are the authors whose gender could not be determined.

Assessing and Correcting Neighborhood Socioeconomic Spatial Sampling Biases in Citizen Science Mosquito Data Collection
<p>Reporting data from the Mosquito Alert citizen science system, active catch basin surveillance, and mosquito trap surveillance used in "Assessing and Correcting Neighborhood Socioeconomic Spatial Sampling Biases in Citizen Science Mosquito Data Collection."</p> <p>The file named mosquito_alert_adult_bite_reports_Barcelona_2014_2023.Rds includes all adult mosquito and mosquito bite reports received from Barcelona Municipality from the start of the Mosqiuto Alert project in 2014 through the end of 2023. The file named mosquito_alert_validated_albopictus_reports_Barcelona_2014_23.Rds includes all expert-validated <em>Ae. albopictus </em>reports received from Barcelona Municipality during the same time period. The data is stored as RDS files and contain the following fields:</p> <ul> <li><strong>year </strong>- the year in which the report was made. Class = dbl.</li> <li><strong>date </strong>- the date om which the report was made. Class = date.</li> <li><strong>type </strong>- the report type, either adult mosquito ("adult") or mosquito breeding site ("site"). Class = chr.</li> <li><strong>lon</strong> - the longitude of the report location. Class = dbl.</li> <li><strong>lat</strong> - the latitude of the report location.

The data is stored in an RDS file with the following fields:</p> <ul> <li><strong>any_reports </strong>- dummy variable indicating whether any Mosquito Alert adult mosquito or mosquito bite reports were sent through Mosquito Alert from within 200 m of the catch basin drain during the year in which the ASPB detected mosquito activity in hte catch basin drain. Class = lgl.</li> <li><strong>se_expected</strong> - sampling effort for the 0.025 degree lon/lat sampling cell in which the catch basin drain lies during the year in which the ASPB detected mosquito activity in the drain. This value is taken from the SE_expected variable in the sampling_effort_daily_cellres_025.csv.gz file available at https://zenodo.org/records/12602985. Sampling effort is estimated as the expected number of participants sending at least one report from the cell during the day in question given the the number of participants recorded in the cell that day and the amount of time elapsed since each one began participating in the project.
