This data collection is an expanded version of UNITED STATES SUPREME COURT JUDICIAL DATABASE, 1953-1996 TERMS (ICPSR 9422), encompassing all aspects of United States Supreme Court decision-making from the beginning of the Vinson Court in 1946 to the end of the Warren Court in 1968. Two major differences distinguish the expanded version of the database from the original collection: the addition of data on the decisions of the Vinson Court, and the inclusion of the conference votes of the Vinson and Warren courts. Whereas the original collection contained only the vote as reported in the UNITED STATES SUPREME COURT REPORTS, the expanded database includes all votes cast in conference. Concomitant with the expansion of the database is a shift in its basic unit of analysis. The original collection contained every case in which at least one justice wrote an opinion, and cases without opinions were excluded. This version includes every case in which the Court cast a conference vote, with and without opinions. The justices cast many more votes than they wrote opinions, and hence, the number of Warren Court records in this version increased by more than a factor of two over the original version. As in the original collection, distinct aspects of the Court's decisions are covered by six types of variables: (1) identification variables including case citation, docket number, unit of analysis, and number of records per unit of analysis, (2) background variables offering information on origin of case, source of case, reason for granting cert, parties to the case, direction of the lower court's decision, and manner in which the Court takes jurisdiction, (3) chronological variables covering date of term of court, chief justice, and natural court, (4) substantive variables including multiple legal provisions, authority for decision, issue, issue areas, and direction of decision, (5) outcome variables supplying information on form of decision, disposition of case, winning party, declaration of unconstitutionality, and multiple memorandum decisions, and (6) voting and opinion variables pertaining to the vote in the case and to the direction of the individual justices' votes.

Durting the 2020 United States Supreme Court term, Justice Clarence Thomas wrote ** opinions for the Supreme Court of the United States - the most out of any justice. In comparison, Justice Elena Kagan wrote ** opinions, including *** opinions of the Court and ***** dissents.

The Supreme Court Observer’s Statistics Pack 2018 (“Stat Pack”) is the first in an annual series that aims to collate, analyze and present a quantitative data overview of the work of the Supreme Court of India. While the Supreme Court publishes data on a monthly, quarterly and annual basis, this information is presented in dour and non-intuitive formats. We draw inspiration from ‘The Statistics’ of the Harvard Law Review and ‘Stat Pack’ of the SCOUTS Blog and adapt their analytical frameworks to look at the available data on the Supreme Court of India.

For the 2020 Supreme Court term, Chief Justice Roberts and Justice Kavanaugh were in agreement on **** percent of rulings. In contrast, the Chief Justice and Justice Sotomayor, the Court's most liberal justice, agreed on **** percent of rulings.

This data collection encompasses all aspects of United States Supreme Court decision-making from the beginning of the Warren Court in 1953 to the completion of the most recent term of the Rehnquist Court. In this collection, distinct aspects of the Court's decisions are covered by six types of variables: (1) identification variables including citations and docket numbers, (2) background variables offering information on how the Court took jurisdiction, origin and source of case, and the reason the Court granted cert, (3) chronological variables covering date of decision, Court term, and natural court, (4) substantive variables including legal provisions, issues, and direction of decision, (5) outcome variables supplying information on disposition of case, winning party, formal alteration of precedent, and declaration of unconstitutionality, and (6) voting and opinion variables pertaining to how individual justices voted, their opinions and interagreements, and the direction of their votes.

The purpose of this data collection was to record information about the cases, litigants, amicus participants, and the opinions decided by the Supreme Court under the tenure of Chief Justices Earl Warren (1953-1969) and Warren Burger (1969-1986) and others through 1993. The approach of this study was to proceed deductively, rather than seek to infer values of a particular group of justices. This method allows the investigation of value conflicts that are not litigated, as well as the value conflicts represented in Supreme Court opinions. Opinions are coded on the basis of their literal content, and the data are organized around the opinions. There are eight types of opinions. Within each type, up to six topics are coded, and within each topic, up to two values are coded. There are three integrated parts to this study, each of which can be linked to the other files by specific variables. Part 1, Supreme Court Database, contains basic case attributes from UNITED STATES SUPREME COURT JUDICIAL DATABASE, 1953-1993 TERMS (ICPSR 9422) and the opinions given in the cases. Part 2, Briefs, gives information on the filers and co-filers for cases in which amicus curie briefs were filed. Part 3, Groups, lists the litigants' names. The distinct aspects of the Court's decisions are covered by six types of variables in Part 1: (1) identification variables including case citation, docket number, unit of analysis, and number of records per unit of analysis, (2) background variables offering information on origin of case, source of case, reason for granting cert, parties to the case, direction of the lower court's decision, and manner in which the Court takes jurisdiction, (3) chronological variables covering date of term of court, chief justice, and natural court, (4) substantive variables including multiple legal provisions, authority for decision, issue, issue areas, and direction of decision, (5) outcome variables supplying information on form of decision, disposition of case, winning party, declaration of unconstitutionality, and multiple memorandum decisions, and (6) voting and opinion variables pertaining to the vote in the case and to the direction of the individual justices' votes.

In 2011, a historic Supreme Court decision mandated that the state of California substantially reduce its prison population to alleviate overcrowding, which was deemed so severe as to preclude the provision of adequate healthcare. To comply, California passed the Public Safety Realignment Act (Assembly Bill [AB] 109), representing the largest ever court-ordered reduction of a prison population in U.S. history. AB109 was successful in reducing the state prison population; however, although the policy was precipitated by inadequate healthcare in state prisons, no studies have examined its effects on prisoner health. As other states grapple with overcrowded prisons and look to California’s experience with this landmark policy, understanding how it may have impacted prisoner health is critical. We sought to evaluate the effects of AB109 on prison mortality and assess the extent to which policy-induced changes in the age distribution of prisoners may have contributed to these effects. To do so, we used prison mortality data from the Bureau of Justice Statistics and the California Deaths in Custody reporting program and prison population data from the National Corrections Reporting Program to examine changes in overall prison mortality, the age distribution of prisoners, and age-adjusted prison mortality in California relative to other states before and after the implementation of AB109. Following AB109, California prisons experienced an increase in overall mortality relative to other states that attenuated within three years. Over the same period, California experienced a greater upward shift in the age distribution of its prisoners relative to other states, suggesting that the state’s increase in overall mortality may have been driven by this change in age distribution. Indeed, when accounting for this differential change in age distribution, mortality among California prisoners exhibited a greater reduction relative to other states in the third year after implementation. As other states seek to reduce their prison populations to address overcrowding, assessments of California’s experience with AB109 should consider this potential improvement in age-adjusted mortality.
