Finding Data: Data on Tonga

ACCESS TO THESE DATA FILES ARE RESTRICTED TO CURRENTLY ENROLLED/EMPLOYED MEMBERS OF PRINCETON UNIVERSITY.

  • Committee to Protect Journalists
    Provides data on journalists killed, imprisoned, exiled, or missing. Also includes attacks on the press.

  • Comparative Survey of Freedom, 1972-1976
    Contains information gathered in 5 annual surveys that assessed the degree of freedom in 218 nations and dependencies. Was carried out under the auspices of Freedom House, New York City. The number of cases with data varies from year to year, due to annexation, amalgamation, or the addition of further territories to the roster. Data includes assessments of the political and civil rights of the general population (using a seven-point scale, i.e., 1, most freedom, to 7, least freedom), an overall freedom rating for the country (using a three-point scale, i.e, free, partly free, and not free), and the direction in which this rating appeared to be moving. Surveys after 1972 have added variables that indicate whether a change in the evaluation since the previous survey was due to internal events in the country or to new information about existing conditions. Before 1973, only the presence or absence of change is noted. Thereafter, an increase in the number of coding categories enables the direction of the change to be recorded. The 1976 data include 4 additional variables applicable to 142 cases and provide information about the system of government and the economy of most of the nations studied.

A series of variables focuses on freedom and barriers to freedom, including freedom of peaceful assembly and association, mail censorship, women's rights, freedom of information and technology, freedom of political opposition, and freedom of the press. Compulsory membership in state organizations and political parties and compulsory religion in schools are addressed as well.

  • Determinants of Aid in the Post-Cold War Era
    Estimates the responsiveness of aid to recipient countries' economic and physical needs, civil/political rights, and government effectiveness.

Finds that aid and per capita income have been negatively related, while aid has been positively related to infant mortality, rights, and government effectiveness.

  • GDELT Project
    GDELT monitors print, broadcast, and web news media in over 100 languages from across every country in the world to keep continually updated on breaking developments anywhere on the planet. Its historical archives stretch back to January 1, 1979 and update daily (soon to be every 15 minutes). Through its ability to leverage the world's collective news media, GDELT moves beyond the focus of the Western media towards a far more global perspective on what's happening and how the world is feeling about it. "The GDELT Project is an initiative to construct a catalog of human societal-scale behavior and beliefs across all countries of the world, connecting every person, organization, location, count, theme, news source, and event across the planet into a single massive network that captures what's happening around the world, what its context is and who's involved, and how the world is feeling about it, every single day."

  • Global Bilateral Migration Database

  • Global Digital Activism Data Set, February 2013
    Features coded cases of online digital activism from 151 countries and dependent territories. Several features from each case of digital activism were documented, including the year and month that online action commenced, the estimated age and country of origin of the initiator(s), the geographic scope of their campaign, and whether the action was online only, or also featured offline activities. Researchers were interested in the number and types of software applications that were used by digital activists. Specifically, information was collected on whether software applications were used to circumvent censorship or evade government surveillance, to transfer money or resources, to aid in co-creation by a collaborative group, or for purposes of networking, mobilization, information sharing, or technical violence (destructive/disruptive hacking). The collection illustrates the overall focus of each case of digital activism by defining the cause advanced or defended by the action, the initiator's diagnosis of the problem and its perceived origin, the identification of the targeted audience that the campaign sought to mobilize, as well as the target whose actions the initiators aimed to influence. Finally, each case of digital activism was evaluated in terms of its success or failure in achieving the initiator's objectives, and whether any other positive outcomes were apparent.

  • Global Entrepreneurship Monitor (GEM) Adult Population Survey Data Set, 1998-2012
    Designed to capture various aspects of firm creation and entrepreneurship across countries.

  • International Military Intervention (1946-2005)
    Updates International Military Intervention (IMI), 1946-1988. This newer study documents 447 intervention events from 1989 to 2005. To ensure consistency across the full 1946-2005 time span, the original coding procedures were followed. The data collection thus "documents all cases of military intervention across international boundaries by regular armed forces of independent states" in the international system). "Military interventions are defined operationally in this collection as the movement of regular troops or forces of one country inside another, in the context of some political issue or dispute". As with the original IMI (OIMI) collection, the 1989-2005 dataset includes information on actor and target states, as well as starting and ending dates. It also includes a categorical variable describing the direction of the intervention, i.e., whether it was launched in support of the target government, in opposition to the target government, or against some third party actor within the target state's borders. The intensity of the military intervention is captured in ordinal variables that document the scale of the actor's involvement, "ranging from minor engagement such as evacuation, to patrols, act of intimidation, and actual firing, shelling or bombing". Casualties that are a direct result of the military intervention are coded as well. A novel aspect of IMI is the inclusion of a series of variables designed to ascertain the motivations or issues that prompted the actor to intervene, including to take sides in a domestic dispute in the target state, to affect target state policy, to protect a socio-ethnic or minority group, to attack rebels in sanctuaries in the target state, to protect economic or resource interests, to intervene for strategic purposes, to lend humanitarian aid, to acquire territory or to dispute its ownership, and to protect its own military/diplomatic interests. The variable, civilian casualties, which complements IMI's information on the casualties suffered by actor and target military personnel has been added. OIMI variables on colonial history, previous intervention, alliance partners, alignment of the target, power size of the intervener, and power size of the target have been deleted.
