Overview

Population Services International (PSI) is a United States-based 501(c)(3) global health organization. Founded in 1970, it originally concentrated on international family planning, contraception, and access to safe abortion services. Over time, it expanded into a broad health-development organization working on malaria, child survival, HIV, reproductive health, and other public-health priorities. PSI’s operating model combines several elements that are often managed separately by governments, charities, and commercial companies. It develops or distributes health products, supports clinical and community services, and uses behavior-change communications to encourage people to adopt healthier practices and seek appropriate care. The organization has historically applied social-marketing techniques, using consumer-oriented branding, distribution networks, and private-sector partnerships to make health commodities more accessible in countries where public systems may not reach all communities. The organization was created by American entrepreneur and philanthropist Phil Harvey together with British physician Tim Black and Jean Black. Before PSI was established, the three founders created Adam and Eve, a retail and mail-order business selling condoms and sex-related products. They intended to use commercial profits to support family-planning work in developing countries. This connection between enterprise and public-health programming became an important feature of PSI’s early funding and operating philosophy. PSI’s first major international experiment was a contraceptive social-marketing program in Kenya, established while Tim and Jean Black lived there from 1970 to 1974. The program received support from the United States Agency for International Development and other agencies and subsequently provided a model for expansion into additional African countries. PSI’s international reach grew further in the 1970s, including through operations in Southeast Asia and Oceania and the establishment of affiliated entities in Europe and Australia. The organization’s historical work also intersected with the development of Marie Stopes International, now known as MSI Reproductive Choices. In the mid-1970s, a PSI-associated European family-planning organization took over the financially failed Marie Stopes Foundation and renamed it Marie Stopes International. Although MSI later developed as a separate organization, PSI founders Tim Black and Phil Harvey remained associated with its leadership for many years. PSI’s later program portfolio broadened beyond reproductive health. Its work has included malaria prevention and treatment, child-health interventions, HIV services, and other programs intended to improve health outcomes among populations facing poverty, limited infrastructure, or barriers to care. The organization has worked with national governments, bilateral donors, multilateral institutions, foundations, companies, and local affiliates. PSI’s headquarters are in Washington, D.C., and it has European offices in Amsterdam. The reference material describes a workforce consisting of U.S.-based staff, overseas expatriate personnel, and thousands of employees working through local PSI affiliates. Major sources of support have included the governments of the United States, United Kingdom, Germany, and the Netherlands, the Global Fund, United Nations agencies, private foundations, corporations, and individual donors. The organization has received both external recognition and critical evaluation. Peter Singer has identified PSI as an effective organization in the fight against extreme poverty. GiveWell reviewed PSI several times and initially listed it among its recommended charities, but later concluded that the available evidence did not clearly demonstrate the impact PSI intended to achieve, while still crediting the organization for focusing on interventions with established potential and monitoring implementation. PSI has also used public figures and celebrity ambassadors to increase awareness of global-health issues, support advocacy, and introduce donors and policymakers to its field programs.

History

Population Services International was founded in 1970 in Chapel Hill, North Carolina, by Phil Harvey, Tim Black, and Jean Black. Harvey was an American entrepreneur and philanthropist, while Tim Black was a British physician who had worked in several countries, including the United Kingdom, Rhodesia, and New Guinea. The founders had met while pursuing graduate studies in family planning and population dynamics at the University of North Carolina. Before creating PSI, Harvey and the Black family established Adam and Eve, a retail and mail-order business selling condoms and sex aids in the United States and abroad. The founders used profits from that business to support family-planning programs in developing countries. PSI was then formed as a charitable not-for-profit organization, giving the founders a dedicated institutional structure for international health work. Harvey served as PSI’s executive director from 1970 through 1977 and remained on its board until 2003. Tim and Jean Black became the organization’s first field leaders. From 1970 to 1974 they lived in Kenya, where they established a PSI contraceptive social-marketing pilot. The project combined family-planning education with the distribution of contraceptives through channels intended to make products affordable and available beyond conventional clinical settings. With support from USAID and other agencies, the Kenyan model was subsequently expanded into other African countries. PSI continued to develop its international structure during the 1970s. In 1971, Australian physician Geoffrey Davis joined the board. In 1974 he became project director for PSI’s Southeast Asia and Oceania activities, which were incorporated as Population Services International (Australasia) Ltd. The Australasian operation was initially based in offices associated with Davis’s clinic in Potts Point, Sydney. Davis led the regional project for roughly a decade and later served as director of PSI Australia until his retirement in 1988. The same year, Tim and Jean Black established a European PSI branch in London under the name Population Services Family Planning Programme Ltd. By 1976, that organization had taken over the financially failed Marie Stopes Foundation and renamed it Marie Stopes International. Marie Stopes International, now MSI Reproductive Choices, later became an independent international reproductive-health organization, although PSI founders remained connected with its leadership for extended periods. From its original concentration on contraception and reproductive health, PSI expanded its programmatic scope. Its work came to include malaria prevention and treatment, child survival, HIV, and other public-health interventions. The organization’s approach retained a strong emphasis on reaching populations underserved by conventional health systems. It used health products, clinical services, communications, social marketing, and partnerships with public and private institutions to influence health behavior and increase access to care. In its mature form, PSI operated from world headquarters in Washington, D.C., with European offices in Amsterdam and a network of local affiliates. The organization’s funding base included government donors in the United States, United Kingdom, Germany, and the Netherlands, as well as the Global Fund, United Nations agencies, foundations, corporations, and individual contributors. The reference material describes a workforce made up of U.S. employees, overseas expatriate staff, and approximately thousands of local affiliate employees. PSI has also invested in advocacy and public visibility. It participated in the U.S. Global Leadership Coalition, a Washington-based coalition advocating for international-affairs and development funding. Celebrity ambassadors, including Ashley Judd, Mandy Moore, and Debra Messing as of 2017, supported awareness activities, visited field programs, participated in conferences, and advocated for global-health funding. External assessments have been mixed but substantive. Philosopher Peter Singer has endorsed PSI as highly effective in work against extreme poverty. GiveWell reviewed PSI in 2007, 2009, and 2011. Although earlier assessments treated PSI as a leading charity, the later review found that the evidence did not clearly demonstrate the impact the organization intended to achieve. GiveWell nevertheless credited PSI with selecting programs with plausible evidence of effectiveness and with monitoring program implementation. This combination of operational recognition and evidentiary scrutiny reflects the broader challenge faced by international health organizations: translating large-scale delivery and social-marketing activity into clearly measured population-level outcomes.

  • Reproductive health · 1970

    Contraceptive social-marketing products

    PSI’s earliest and most characteristic offering was the distribution and promotion of contraceptives through social-marketing systems. These programs sought to combine consumer-oriented product distribution with family-planning information and access points outside the formal public-health network. The approach was first tested in Kenya and later expanded to other countries.

  • Global health

    Malaria interventions

The reference material identifies malaria as one of the organization’s major program areas, although it does not specify individual product brands.

  • Child health

    Child-survival programs

    PSI develops and implements interventions aimed at improving child survival. These may include products, services, community delivery, and behavior-change communications, but the supplied sources do not identify a single standardized PSI child-health product line.

  • HIV prevention and care

    HIV services

    HIV is one of PSI’s identified program areas. The organization’s model can include clinical services, prevention communications, linkage to care, and locally adapted delivery partnerships. The reference material does not provide enough detail to identify specific current HIV products or branded programs.

  • Clinical services · 1970

    Reproductive-health clinical services

    PSI began as a provider and promoter of reproductive-health services, including contraception and safe abortion services. Its reproductive-health work has combined clinical delivery, commodities, counseling, and communications designed to improve access for people in high-need settings.
