  • According to a 2018 survey that was conducted by the Economist and the Kaiser Family Foundation (KFF), "more than 2 in 10 adults or 22% of adults in the United States say they always or often feel lonely, lack companionship, or feel left out or isolated."
  • These figures illustrate the seriousness of loneliness in the United States. Loneliness is accompanied by equally alarming warnings i.e. it is stunting the lives of Americans and outright killing people.
  • Another survey by Cigna reported that almost half of Americans always or sometimes feel alone (46%) or left out (47%) while a whole 54% of Americans feel they always or sometimes feel that no one knows them well.
  • Scientists have reported that loneliness "is emotionally painful and can lead to psychiatric disorders like depression, anxiety, schizophrenia, and even hallucinatory delirium."
  • In 2015, researchers at UCLA discovered that loneliness and social isolation triggers cellular changes that result in chronic inflammation resulting in exposure to serious physical conditions such as heart disease, stroke, metastatic cancer, and Alzheimer’s disease.
  • Another 2015 analysis that used data from 70 studies that followed 3.4 million people over 7 years reported that lonely people had a 26% higher risk of dying and this figure rose to 32% if the lonely people lived alone.
  • Over the last 50 years, the number of single households in the United States that consist of one person have doubled. Today, this type of households is the second most common household type in the country.
