    "description": "Dying without anyone at all to inherit is the kind of fear that surfaces in estate planning advertisements and loneliness discourse but rarely in rigorous surveys. Most people assume it happens only to hermits or the very elderly. The cultural image is of an eccentric recluse whose fortune escheats to the state -- a rare curiosity, not a plausible personal outcome. In practice, intestacy law casts a very wide net for heirs (second cousins, half-siblings, step-relations in some jurisdictions), which makes the \"truly no one\" scenario considerably rarer than the \"no will\" scenario that dominates headlines.\n",

    "assumptions": "The \"no one to inherit\" scenario requires the intersection of several conditions: no surviving spouse, no children, no parents, no siblings, no nieces/nephews, and no other identifiable relatives within the intestate succession hierarchy. Research from Penn State (Margolis and Verdery, analyzing HRS/NLSY survey data 1998-2010) found that 6.6% of US adults 55+ have neither a spouse nor biological children alive, and that just 1% of older Americans have essentially no relatives at all alive -- including a spouse, partner, children, or biological parents or siblings. That 1% \"no relatives at all\" figure is the one that maps to the escheatment scenario; the 6.6% \"no spouse or biological children\" figure is much broader because many of those adults still have siblings, nieces, nephews, or parents who inherit under intestacy law. We therefore take ~1% as the central lifetime probability, directly from the Penn State source's stated \"1 percent\" figure for older adults with essentially no living relatives. Intestacy statutes in all 50 states search exhaustively for distant relatives before escheatment occurs, and the Caring.com 2025 survey found only 24% of Americans have a will (so ~76% die intestate) -- but intestacy does not mean no heir, it means the state assigns heirs by statute. True escheatment (property reverting to the state for lack of any identifiable heir) is described in legal literature as \"rare.\" The uncertainty band is asymmetric and wide because \"no identifiable heir\" depends on how hard the state searches and how distant a relative counts, and because the kinless share is projected to rise for future cohorts (Penn State projects the share of non-Hispanic whites lacking close kin to roughly double by 2060). The lower bound reflects that professional heir-search firms locate relatives even for many nominally kinless decedents.\n",

      "calculation_notes": "Pew's 2024 survey documents rising expected childlessness, but childlessness alone does not mean dying without an heir -- most childless adults have siblings, parents, or other relatives. The 47% figure is the share of childless adults under 50 who say they are unlikely to ever have kids (up from 37% in 2018); it is not the proportion of all under-50 adults who currently have no children. For women 45-50 (near the end of fertility), the Census Bureau reports 14.9% are childless as of 2024, down from 16.7% in 2014. The Pew data is used here as a trend indicator: a growing share of childless younger adults expect to remain childless, which, combined with declining marriage rates and smaller family sizes, will increase the share of future elderly with no close relatives. This supports an upward-skewed uncertainty band relative to the current ~1% observed kinless-with-no-relatives rate.\n",

      "calculation_notes": "The 76% intestacy rate is frequently conflated with \"dying without an heir,\" but these are fundamentally different conditions. Intestacy means the state assigns heirs according to a statutory hierarchy (spouse > children > parents > siblings > nieces/nephews > grandparents > aunts/uncles > cousins, etc.). In nearly all intestate cases, an heir exists somewhere in this chain. True escheatment -- where the state inherits because no heir can be found -- occurs only when the entire hierarchy is exhausted. States collectively hold ~$70 billion in unclaimed property, but most of this is dormant bank accounts and uncashed checks, not escheated estates. The Caring.com data is used here to establish the denominator of the problem: most Americans do not plan their estates, but most still have statutory heirs.\n",

  "caveats": "\"No one to inherit\" is a spectrum, not a binary. Intestacy statutes in all US states search for relatives out to very distant degrees of kinship before escheatment occurs. A person with a living third cousin they have never met is not, legally, dying without an heir. The ~1% central estimate refers to the stricter scenario: no identifiable relative can be found through reasonable diligent search. The number is rising because of converging demographic trends -- increasing childlessness, declining marriage rates, smaller sibship sizes, and longer lifespans that allow individuals to outlive their entire family network. The Penn State figure that just 1% of older Americans have essentially no living relatives at all is the most relevant data point, but even this may overstate the escheatment rate because professional heir-search firms often locate relatives the decedent did not know existed. The emotional dimension -- dying without anyone who *cares* about inheriting, as opposed to anyone who *legally can* -- is not captured by these statistics and is probably a larger number.\n",
