    "description": "Most parents who worry about toddler safety think about stairs, electrical outlets, and swimming pools. Window blind cords register as background furniture, not hazards. The few parents who do know about the risk often frame it as an artifact of older homes — \"we got cordless blinds, so we're fine\" — without realizing that most US homes still contain legacy looped-cord blinds in at least one room. The hazard is effectively invisible: a child can become entangled silently, and strangulation can be complete in minutes, often while the child is in a room the parent left for less than ten minutes. The gap between perceived and actual risk runs almost entirely in the direction of underestimation, not panic.\n",

Annual risk per child: 9 / 19,000,000 = 4.7e-7 per year. Over the 5-year at-risk window (birth to age 5): 4.7e-7 × 5 = 2.4e-6. This is the figure used as lifetime_us_adult (scope: subgroup_lifetime). The Pediatrics 2018 study (Onders et al.) found 271 deaths over 26 years (1990-2015) = ~10.4 per year, which is consistent with the CPSC figure and slightly increases the central estimate. The earlier JAMA 1997 study (Rauchschwalbe & Mann) found 0.14 per 100,000 children under 3 per year during 1981-1995, equivalent to roughly 12 deaths/year when applied to the ~8.5 million US children under 3 at the time. Using 9/year as the headline and 8-12/year as the plausible range yields uncertainty bounds of approximately 1.0e-6 to 5.0e-6.\n",

The Rauchschwalbe/Mann study also established that infants became entangled primarily during nap time (cord loops reaching sleeping surfaces), while toddlers were more often suspended after falling or jumping from height near a window — two mechanistically distinct scenarios that the CPSC addressed in its 2018 ANSI/WCMA standard.\n",

  "caveats": "The ~9 deaths/year figure reflects a declining trend from the ~12/year estimated in the 1981-1995 JAMA study, likely due to partial industry adoption of safer cord designs following voluntary standards. The figure applies primarily to homes with pre-2018 looped-cord window coverings; cordless and motorized blinds sold under ANSI/WCMA A100.1-2018 or the CPSC's 2023 mandatory rule (16 CFR 1260, effective May 30, 2023) substantially eliminate the mechanism. The scope is subgroup_lifetime because this is a child-specific risk with a narrow age window (under 5); the figure should not be interpreted as a general adult lifetime probability. Reporting is likely incomplete — the CPSC notes that incidental strangulation deaths are underreported to surveillance systems, and the 1997 JAMA study specifically found the number of cases was higher than official records suggested.\n",
