Overview
Negative Population Growth (NPG) is a United States nonprofit organization focused on population policy, demographic growth, immigration, fertility, and the environmental and resource pressures that it associates with population expansion. Founded in 1972 by Don Mann, the organization emerged from concerns that the population-stabilization approach associated with Zero Population Growth did not go far enough. Its name expresses a preference for a gradual decline in population rather than merely reaching a stable level. NPG's central position is that both the United States and the world have populations above what the organization considers sustainable or desirable. It has stated that an optimal population for the United States would be approximately 150 million to 200 million people, and that an optimal global population would be approximately two billion to three billion. These figures are normative targets used in the organization's advocacy rather than official demographic forecasts or government population standards. The organization promotes a combination of lower fertility and reduced immigration as means of moving toward a smaller United States population. It has advocated policies intended to reduce the national fertility rate to approximately 1.5 births per woman. It has also supported sharply lower levels of immigration, citing an annual target of roughly 100,000 to 200,000 immigrants compared with levels that it describes as exceeding 1.5 million per year. Its agenda therefore differs from population-stabilization groups that focus primarily on family planning, reproductive health, or long-term demographic balance, because NPG places particularly strong emphasis on population reduction and immigration limitation. NPG presents population growth as connected to pressures on natural resources, land, infrastructure, environmental quality, and public services. Its advocacy is situated within the broader population-concern movement, which includes debates over carrying capacity, consumption, ecological limits, and the relationship between demographic change and environmental sustainability. The organization has also been associated with arguments that population growth can intensify domestic resource and quality-of-life problems. The organization has operated primarily as a United States policy advocacy group rather than as a consumer-facing brand or commercial enterprise. Publicly available reference material identifies it as a nonprofit and reports that NPG claimed more than 25,000 members in 2011, although the precise definition of membership was not clear. Information about its present leadership, staffing, finances, legal structure, and current membership is not established in the supplied reference material. NPG's official website remains the principal organizational reference identified here.
History
Negative Population Growth was established in the United States in 1972 by Don Mann. Its creation reflected a disagreement with the direction of the population-control movement of the period. Mann believed that Zero Population Growth, whose objective was generally understood as achieving demographic stability, did not adequately address the environmental, economic, and resource consequences of continued population growth. The new organization therefore adopted the more explicit goal of negative population growth: a gradual reduction in population over time. From its founding, NPG treated population size as a central public-policy issue rather than solely as a matter of individual reproductive choice. The organization's arguments connected demographic growth with finite resources, environmental degradation, land use, infrastructure demands, and pressures on living standards. Its approach has generally emphasized the United States while also advancing a global population objective. NPG has stated that the United States would ideally contain between 150 million and 200 million people, while the desirable global population would be between two billion and three billion. These targets form part of the organization's advocacy framework. To move toward them, NPG has promoted policies intended to lower the United States fertility rate to 1.5 births per woman and has argued for substantially reducing immigration. It has described an annual immigration level of approximately 100,000 to 200,000 as preferable to levels above 1.5 million per year. The organization's program places immigration policy alongside fertility reduction, making it distinct from population organizations that concentrate mainly on voluntary family planning, reproductive healthcare, or stabilization at replacement-level fertility. NPG's public position is that both natural increase and immigration contribute to population growth and should therefore be addressed in a comprehensive population policy. In 2011, NPG claimed that its membership exceeded 25,000. Available reference material does not clarify how the organization defined membership or independently verify the figure. The supplied sources also do not establish a detailed chronology of its campaigns, leadership changes, organizational restructuring, funding, or formal partnerships. NPG is best characterized on the available evidence as a United States nonprofit advocacy organization that has maintained a consistent population-reduction orientation since its establishment.

Products and positioning
NPG positions itself as a population-reduction advocacy organization, distinguishing its program from population-stabilization approaches by arguing that the United States and the world should gradually reduce their populations. Its policy framework combines demographic, environmental, resource, and immigration concerns.
Advocacy · 1972
Population-policy advocacy
NPG's principal activity is advocacy for a gradual reduction in United States and global population. Its policy position treats demographic decline as a desirable long-term objective rather than limiting its goal to population stabilization.
Policy research and education
Fertility-reduction policy proposals
The organization promotes policies intended to reduce the United States fertility rate to approximately 1.5 births per woman, presenting lower fertility as one component of a broader strategy for reducing population size.
Immigration policy advocacy
Immigration-reduction policy proposals
NPG advocates substantially lower immigration to the United States and has identified an annual range of approximately 100,000 to 200,000 as a target. The proposal is presented as a means of slowing and eventually reversing population growth.
