The Gender Equality Index 2023 presents the EU in relation to gender equality amid crises and uncertainties. In recent years, the world has been hit by repeated shocks and multiple crises. What remains constant is the fact that when crisis strikes, women and girls suffer disproportionally. The crises and shocks continuously threaten to create new challenges and reverse years of...

The GREENA step-by-step toolkit provides practical know-how to assess gender impacts and the implementation of gender-responsive evaluation of EU policies and programmes. The toolkit has been contextualised to support the evaluation of the European Green Deal policies with a gender perspective, given its relevance as a current EU priority and the urgency to ensure a gender-responsive green transition.

EIGE, in its contribution to a public consultation on the design of transparency reports under the Digital Services Act (DSA), has highlighted the need to include gender-based measurement instruments.

Our interactive map shows state-based immigration data across all 50 states, the District of Columbia, and Puerto Rico. Map features data on such topics as I-94 non-immigrant arrivals, naturalizations, refugee arrivals, total asylum grants, and arrivals and adjustments.

The data table for International Trade Intellectual Property Rights Seizures includes total seizures made by U.S. Customs and Border Protection (CBP) and Immigration and Customs Enforcement (ICE) Homeland Security Investigations.

The Department of Homeland Security (DHS) Use of Force Incidents report provides breakdowns of the number of DHS law enforcement use of force incidents, types of force used, and subject and officer injuries.

Includes detailed data tables on such topics as encounters by type and region; encounters by agency and citizenship, family status and sector; arrests by citizenship and criminality; repatriations; and more.

The Yearbook of Immigration Statistics is a collection of tables that provides data on foreign nationals who were granted lawful permanent residence, were admitted into the United States on a temporary basis, applied for asylum or refugee status, or were naturalized.

Created in 2023, the Office of Homeland Security Statistics (OHSS) provides reports and statistical data covering a range of topics. We currently have data and reports on immigration, law enforcement, and international trade. Over time, we will cover all Department of Homeland Security's (DHS) statistical data, including cybersecurity, emergency management, infrastructure protection, maritime, screening, terrorism and targeted violence, and chemical, biological, radiological, and nuclear threats.

The UNESCO Institute for Statistics (UIS) is the official and trusted source of internationally-comparable data on education, science, culture and communication. As the official statistical agency of UNESCO, the UIS produces a wide range of state-of-the-art databases to fuel the policies and investments needed to transform lives and propel the world towards its development goals. The UIS provides free access to data for all UNESCO countries and regional groupings from 1970 to the most recent year available. The UIS encourages developers and researchers to build websites and applications that make rich use of UIS dissemination data. In addition to a powerful standards-based API, the UIS supports a data browser and a bulk data download service (BDDS).

A comprehensive and easy-to-use browser for viewing and downloading the most popular UIS data and indicators in tables. Data are organized in a tree view by topic and presented using a simple three-dimensional format (indicator, country or region, year). Users can build their own customized tables and export data in Excel format.

Statistics Canada is the national statistical office. The agency ensures Canadians have the key information on Canada's economy, society and environment that they require to function effectively as citizens and decision makers.

The police-reported Crime Severity Index (CSI) increased 2% in 2023. This was the third consecutive annual increase in the CSI, continuing an upward trend that began prior to the COVID-19 pandemic. The Non-violent CSI increased, while the Violent CSI was essentially unchanged from 2022.

The following table lists the number of bases and the number of sequencerecords in each release of GenBank, beginning with Release 3 in 1982.CON-division records are not represented in these statistics: because theyare constructed from the non-CON records in the database, their inclusionhere would be a form of double-counting. Also note that this table is limitedto 'traditional', non-set-based (WGS/TSA/TLS) GenBank records. From 1982 to the present, the number of bases in GenBank has doubledapproximately every 18 months.

Statistics (from German: Statistik, orig. "description of a state, a country")[1][2] is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.[3][4][5] In applying statistics to a scientific, industrial, or social problem, it is conventional to begin with a statistical population or a statistical model to be studied. Populations can be diverse groups of people or objects such as "all people living in a country" or "every atom composing a crystal". Statistics deals with every aspect of data, including the planning of data collection in terms of the design of surveys and experiments.[6]

When census data cannot be collected, statisticians collect data by developing specific experiment designs and survey samples. Representative sampling assures that inferences and conclusions can reasonably extend from the sample to the population as a whole. An experimental study involves taking measurements of the system under study, manipulating the system, and then taking additional measurements using the same procedure to determine if the manipulation has modified the values of the measurements. In contrast, an observational study does not involve experimental manipulation.

Two main statistical methods are used in data analysis: descriptive statistics, which summarize data from a sample using indexes such as the mean or standard deviation, and inferential statistics, which draw conclusions from data that are subject to random variation (e.g., observational errors, sampling variation).[7] Descriptive statistics are most often concerned with two sets of properties of a distribution (sample or population): central tendency (or location) seeks to characterize the distribution's central or typical value, while dispersion (or variability) characterizes the extent to which members of the distribution depart from its center and each other. Inferences made using mathematical statistics employ the framework of probability theory, which deals with the analysis of random phenomena.

A standard statistical procedure involves the collection of data leading to a test of the relationship between two statistical data sets, or a data set and synthetic data drawn from an idealized model. A hypothesis is proposed for the statistical relationship between the two data sets, and this is compared as an alternative to an idealized null hypothesis of no relationship between two data sets. Rejecting or disproving the null hypothesis is done using statistical tests that quantify the sense in which the null can be proven false, given the data that are used in the test. Working from a null hypothesis, two basic forms of error are recognized: Type I errors (null hypothesis is rejected when it is in fact true, giving a "false positive") and Type II errors (null hypothesis fails to be rejected when an it is in fact false, giving a "false negative"). Multiple problems have come to be associated with this framework, ranging from obtaining a sufficient sample size to specifying an adequate null hypothesis.[7]

Statistical measurement processes are also prone to error in regards to the data that they generate. Many of these errors are classified as random (noise) or systematic (bias), but other types of errors (e.g., blunder, such as when an analyst reports incorrect units) can also occur. The presence of missing data or censoring may result in biased estimates and specific techniques have been developed to address these problems.

Statistics is a mathematical body of science that pertains to the collection, analysis, interpretation or explanation, and presentation of data,[8] or as a branch of mathematics.[9] Some consider statistics to be a distinct mathematical science rather than a branch of mathematics. While many scientific investigations make use of data, statistics is generally concerned with the use of data in the context of uncertainty and decision-making in the face of uncertainty.[10][11]
