Why loneliness matters
Social isolation is one of the strongest predictors of depression, cognitive decline, and premature mortality in later life. In 2023 the U.S. Surgeon General formally declared loneliness a public-health epidemic.

Senior Loneliness: The Data, the Research, the Solutions
We gather trusted data on loneliness and social isolation among older adults — from AARP Foundation, the NIH, NASEM, the WHO, and the U.S. Surgeon General — to show why Campus is needed and what actually works.

How loneliness affects health
Chronic loneliness triggers a stress response and chronic inflammation that damages tissue and weakens immunity — raising the risk of heart disease, hypertension, dementia (including Alzheimer’s), and premature death.
03
Isolation and loneliness are different
Isolation is the objective lack of contact (you can live alone and not feel lonely). Loneliness is the subjective lack of meaningful connection — you can feel it in a crowded city. Effective solutions address both.
04
What works: community-based solutions
Programs built around regular community gathering show statistically significant reductions in loneliness, even on modest budgets. Simply connecting with neighbors lowers the loneliness rate from 61% to 33%.
05
Intergenerational programs
Programs that connect younger people with seniors deliver a double benefit: better well-being and cognition for seniors, and stronger empathy in the younger generation.
06
The Jewish community response
Shabbat, Yom Tov, communal meals, and shared learning form a structure that has historically kept people from being alone. Campus is the modern continuation of that structure.
Frequently asked questions
How common is loneliness among older adults?+
According to AARP Foundation, about 1 in 3 adults age 45+ experience chronic loneliness — roughly 42.6 million Americans, and that group has grown by 5 million over the past decade.
Is loneliness really bad for your health?+
Yes. The U.S. Surgeon General (2023) compared the toll of chronic loneliness to smoking about 15 cigarettes a day. It raises the risk of heart disease, dementia, and premature death.
What actually reduces senior loneliness?+
Regular community gatherings, purposeful activity and volunteering, intergenerational connection, and simple neighborly contact. Connecting with neighbors lowers loneliness from 61% to 33%.
What does Campus do?+
Campus, by Education On The Go Corp, builds community for older adults through Shabbat, learning, nature, and volunteer care — a modern continuation of the Jewish tradition against loneliness.
