This dataset represents the popular last names in the United States for Hispanic.

Between 1982 and September 2024, 82 out of the 151 mass shootings in the United States were carried out by White shooters. By comparison, the perpetrator was African American in 26 mass shootings, and Latino in 12. When calculated as percentages, this amounts to 54 percent, 17 percent, and eight percent respectively. Race of mass shooters reflects the U.S. population Broadly speaking, the racial distribution of mass shootings mirrors the racial distribution of the U.S. population as a whole. While a superficial comparison of the statistics seems to suggest African American shooters are over-represented and Latino shooters underrepresented, the fact that the shooter’s race is unclear in around nine percent of cases, along with the different time frames over which these statistics are calculated, means no such conclusions should be drawn. Conversely, looking at the mass shootings in the United States by gender clearly demonstrates that the majority of mass shootings are carried out by men. Mass shootings and mental health With no clear patterns between the socio-economic or cultural background of mass shooters, increasing attention has been placed on mental health. Analysis of the factors Americans considered to be to blame for mass shootings showed 80 percent of people felt the inability of the mental health system to recognize those who pose a danger to others was a significant factor. This concern is not without merit – in over half of the mass shootings since 1982, the shooter showed prior signs of mental health issues, suggesting improved mental health services may help deal with this horrific problem. Mass shootings and guns In the wake of multiple mass shootings, critics have sought to look beyond the issues of shooter identification and their influences by focusing on their access to guns. The majority of mass shootings in the U.S. involve firearms which were obtained legally, reflecting the easy ability of Americans to purchase and carry deadly weapons in public. Gun control takes on a particular significance when the uniquely American phenomenon of school shootings is considered. The annual number of incidents involving firearms at K-12 schools in the U.S. was over 100 in each year since 2018. Conversely, similar incidents in other developed countries exceptionally rare, with only five school shootings in G7 countries other than the U.S. between 2009 and 2018.

General Overview

I created this dataset originally to preserve NASCAR stage results. NASCAR's official website preserves full stage results, but as of now, only 2023-2025 results are available there. The results from earlier years were removed and links to them redirect to Racing Reference, a site which stores all NASCAR (and many other racing series) results since the beginning of the sport. However, that site only records the top 10 stage finishers for each race (points earning positions). To see full stage 1 and stage 2 finishing orders from 2017 (the first year of stage racing) through 2022, you had to use the Wayback Machine on NASCAR.com...until now.

Originality

• Only publicly available dataset (I'm aware of) that contains NASCAR results and points-per-race data all in one file, so to be useful for analysis and predictive modeling
• Only NASCAR results source containing team names (as opposed to names of owners on Racing Reference)
• Only NASCAR results source with full stage finishing orders going back to 2017 (still looking for complete stage finishing orders, beyond just top 10s, from Race 23 of 2017 through Race 36 of 2019)

Attribute overview

1) year - year in which the observation took place

2) race_num - order of races each season, with 1 being the first and 36 being the last - to include the pre-season Daytona Duel races (which count as a stage), I gave Duel 1 the value '-1' and Duel 2 the value '-2'

3) track - shortened name of the track at which the observation took place - tracks with terrain changes / multiple layouts were considered separate tracks, ex: Bristol and Bristol Dirt, Daytona and Daytona Road Course

4) track_type - 6 different track types including: short tracks (less than 1 mile), short intermediates (more than 1 mile and less than 1.5 miles), intermediates (roughly 1.5 miles / "cookie cutters"), long intermediates (longer than 1.5 miles but not superspeedways or road courses), superspeedways (drafting / pack racing tracks), road course (tracks with both left and right turns) - notably, Atlanta was the only track to change its track type in the observed years, being reconfigured from intermediate to superspeedway in 2022

5) fin - final finishing order of each race

6) start - starting order of each race (no distinction between traditional qualifying and formula / owners-points-based starting lineups)

7) car_num - the number printed on the race car, distinct from all other competitors in each race

8) driver - full name of the driver

9) manu - manufacturer of the car

10) team_name - name of the team which fielded the driver and car in a particular observation

11) laps - number of laps the driver completed in the race

12) laps_led - number of laps the driver led in the race

13) status - 'running' for drivers who finished the race; otherwise, the reason they failed to finish - 'accident' is a synonym for 'crash' (used interchangeably on different sources)

14) points - total points earned in the race - Note 1: drivers who did not declare for Cup points earned 0 points regardless of finishing position - Note 2: disqualified drivers are given last place points, and if there is more than one disqualified driver, they will be ordered by their original finishing position behind everyone else

15) stage_1 - finishing position in stage 1

16) stage-2 - finishing position in stage 2

17) stage_3_or_duel - finishing position in stage 3 (Coca Cola 600 only) or Daytona Duel race (counts as a stage)

18) stage_points - total stage points earned in the race - Note 1: drivers who did not declare for Cup points earned 0 points regardless of stage finishing position, as did disqualified drivers, and Championship 4 drivers in the season finale - Note 2: if a disqualified driver would have earned stage points, their points were given to the next finisher, and so on, so that the original 11th place finisher earns 1 stage point

This dataset comprises physician-level entries from the 1906 American Medical Directory, the first in a series of semi-annual directories of all practicing physicians published by the American Medical Association [1]. Physicians are consistently listed by city, county, and state. Most records also include details about the place and date of medical training. From 1906-1940, Directories also identified the race of black physicians [2].This dataset comprises physician entries for a subset of US states and the District of Columbia, including all of the South and several adjacent states (Alabama, Arkansas, Delaware, Florida, Georgia, Kansas, Kentucky, Louisiana, Maryland, Mississippi, Missouri, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, Virginia, West Virginia). Records were extracted via manual double-entry by professional data management company [3], and place names were matched to latitude/longitude coordinates. The main source for geolocating physician entries was the US Census. Historical Census records were sourced from IPUMS National Historical Geographic Information System [4]. Additionally, a public database of historical US Post Office locations was used to match locations that could not be found using Census records [5]. Fuzzy matching algorithms were also used to match misspelled place or county names [6].The source of geocoding match is described in the “match.source” field (Type of spatial match (census_YEAR = match to NHGIS census place-county-state for given year; census_fuzzy_YEAR = matched to NHGIS place-county-state with fuzzy matching algorithm; dc = matched to centroid for Washington, DC; post_places = place-county-state matched to Blevins & Helbock's post office dataset; post_fuzzy = matched to post office dataset with fuzzy matching algorithm; post_simp = place/state matched to post office dataset; post_confimed_missing = post office dataset confirms place and county, but could not find coordinates; osm = matched using Open Street Map geocoder; hand-match = matched by research assistants reviewing web archival sources; unmatched/hand_match_missing = place coordinates could not be found). For records where place names could not be matched, but county names could, coordinates for county centroids were used. Overall, 40,964 records were matched to places (match.type=place_point) and 931 to county centroids ( match.type=county_centroid); 76 records could not be matched (match.type=NA).Most records include information about the physician’s medical training, including the year of graduation and a code linking to a school. A key to these codes is given on Directory pages 26-27, and at the beginning of each state’s section [1]. The OSM geocoder was used to assign coordinates to each school by its listed location. Straight-line distances between physicians’ place of training and practice were calculated using the sf package in R [7], and are given in the “school.dist.km” field. Additionally, the Directory identified a handful of schools that were “fraudulent” (school.fraudulent=1), and institutions set up to train black physicians (school.black=1).AMA identified black physicians in the directory with the signifier “(col.)” following the physician’s name (race.black=1). Additionally, a number of physicians attended schools identified by AMA as serving black students, but were not otherwise identified as black; thus an expanded racial identifier was generated to identify black physicians (race.black.prob=1), including physicians who attended these schools and those directly identified (race.black=1).Approximately 10% of dataset entries were audited by trained research assistants, in addition to 100% of black physician entries. These audits demonstrated a high degree of accuracy between the original Directory and extracted records. Still, given the complexity of matching across multiple archival sources, it is possible that some errors remain; any identified errors will be periodically rectified in the dataset, with a log kept of these updates.For further information about this dataset, or to report errors, please contact Dr Ben Chrisinger (Benjamin.Chrisinger@tufts.edu).

Tabular data of population by age groups, race and gender, and the poverty by race is attached to the split tract geography to create this split tract with population and poverty data. Split tract data is the product of 2020 census tracts split by 2021 incorporated city boundaries and unincorporated community/countywide statistical areas (CSA) boundaries. The census tract boundaries have been altered and aligned where necessary with legal city boundaries and unincorporated areas, including shoreline/coastal areas. Census Tract:Every 10 years the Census Bureau counts the population of the United States as mandated by Constitution.

City Boundary:City Boundary data is the base map information for the County of Los Angeles. These City Boundaries are based on the Los Angeles County Seamless Cadastral Landbase. The Landbase is jointly maintained by the Los Angeles County Assessor and the Los Angeles County Department of Public Works (DPW). This layer represents current city boundaries within Los Angeles County. The DPW provides the most current shapefiles representing city boundaries and city annexations. True, legal boundaries are only determined on the ground by surveyors licensed in the State of California.Countywide Statistical Areas (CSA): The countywide Statistical Area (CSA) was defined to provide a common geographic boundary for reporting departmental statistics for unincorporated areas and incorporated Los Angeles city to the Board of Supervisors. The CSA boundary and CSA names are established by the CIO and the LA County Enterprise GIS group worked with the Los Angeles County Board of Supervisors Unincorporated Area and Field Deputies that reflect as best as possible the general name preferences of residents and historical names of areas. This data is primarily focused on broad statistics and reporting, not mapping of communities.

The resulting polygon boundary aligned and matched with the legal city boundary whenever possible. Population by age, race/ethnicity and gender are extracted from census data at blocks, and allocated to each area of split tracts by aggregating block-based population count. The poverty population is allocated to split tracts according to population proportion. The tabular data of population by age groups, by ethnic groups and by gender, and the poverty by ethnic groups is then attached to the split tract geography to create this data.Note:1. Population and poverty data estimated as of July 1, 2013. 2. 2010 Census tract and 2020 census tracts are not the same. Similarly, city and community boundary are not the same because boundary is reviewed and updated annually.

Tabular data of population by age groups, race and gender, and the poverty by race is attached to the split tract geography to create this split tract with population and poverty data. Split tract data is the product of 2010 census tracts split by 2017 incorporated city boundaries and unincorporated community/countywide statistical areas (CSA) boundaries. The census tract boundaries have been altered and aligned where necessary with legal city boundaries and unincorporated areas, including shoreline/coastal areas. Census Tract:Every 10 years the Census Bureau counts the population of the United States as mandated by Constitution. The Census Bureau (https://www.census.gov/) released 2010 geographic boundaries data including census tracts for the analysis and mapping of demographic information across the United States. City Boundary:City Boundary data is the base map information for the County of Los Angeles. These City Boundaries are based on the Los Angeles County Seamless Cadastral Landbase. The Landbase is jointly maintained by the Los Angeles County Assessor and the Los Angeles County Department of Public Works (DPW). This layer represents current city boundaries within Los Angeles County. The DPW provides the most current shapefiles representing city boundaries and city annexations. True, legal boundaries are only determined on the ground by surveyors licensed in the State of California.Countywide Statistical Areas (CSA): The countywide Statistical Area (CSA) was defined to provide a common geographic boundary for reporting departmental statistics for unincorporated areas and incorporated Los Angeles city to the Board of Supervisors. The CSA boundary and CSA names are established by the CIO and the LA County Enterprise GIS group worked with the Los Angeles County Board of Supervisors Unincorporated Area and Field Deputies that reflect as best as possible the general name preferences of residents and historical names of areas. This data is primarily focused on broad statistics and reporting, not mapping of communities.

This project will collect online survey data from a representative sample of the working-age population in Catalonia (Spain) to investigate the social class and linguistic competence perceptions of a list of forenames and surnames signalling different ethnic backgrounds. The online survey data will complement experimental data on ethnic discrimination in the labour market from the GEMM audit study, which was conducted in 2017-2018 in five European countries including Spain (Lancee, 2021).

Audit studies are often the main method to uncover direct discrimination in the labour and housing markets. In these type of research designs, we rely on ethnic distinctive forenames and surnames to convey the ethnicity of fictitious applicants to employers and landlords. However, evidence has shown that the names that are often used in audit studies to signal ethnicity also convey information about applicants’ social class and level of education (Gaddis, 2017a, 2017b). This is highly problematic, as most name-based treatments can manipulate more than the relevant characteristic of interest (ethnicity, race or ancestry).

The online survey data collected will examine the social class and the (Spanish and Catalan) linguistic competence perceptions of a list of names used in the GEMM audit study signalling Spanish, Catalan, Ecuadorian, Moroccan, Nigerian and Ugandan ancestry (Lancee et al., 2021).
