In 2022, ~3,700 SUID deaths in the US; 1,040 classified as accidental suffocation and strangulation in bed (ASSB)
“"In 2022, there were about 3,700 sudden unexpected infant deaths (SUID) in the United States. These deaths occur among infants less than 1 year old and have no immediately obvious cause. [...] 1,040 deaths from accidental suffocation and strangulation in bed."”
Calculation notes
1,040 ASSB deaths out of ~3.67 million US live births in 2022 ≈ 28.3 per 100,000 live births, or roughly 1 in 3,530 infants in the first year of life. Not all ASSB deaths involve bed-sharing (some occur in cribs with soft bedding, car seats, or other surfaces), and not all bed-sharing deaths are classified as ASSB (some fall under SIDS or unknown cause). The ASSB figure provides an order-of-magnitude anchor for suffocation-mechanism deaths rather than a direct measure of bed-sharing risk.
Independence note: CDC vital registration data. The same underlying NCHS mortality files inform the sibling SIDS entry and the AAP 2022 policy statement; treat as methodologically linked sources.

~3,700 US sudden unexpected infant deaths in 2022 (SIDS, accidental suffocation and strangulation in bed, and unknown cause)
“"In 2022, there were about 3,700 sudden unexpected infant deaths (SUID) in the United States. These deaths occur among infants less than 1 year old and have no immediately obvious cause. [...] 1,529 deaths from SIDS [...] 1,131 deaths from unknown causes [...] 1,040 deaths from accidental suffocation and strangulation in bed."”
Calculation notes
Anchors the sitting-device subset inside the broader sudden unexpected infant death (SUID) umbrella. The Liaw et al. figure of ~32 sitting-device deaths per year is on the order of 1% of all SUID deaths in a given year, which is why this fear is real but small relative to the SIDS / ASSB bulk of the sleep-related infant death count. Used as the denominator context for comparison_anchors and to position the sitting-device subset against the full SUID umbrella.
Independence note: CDC NCHS mortality data partly feeds the Liaw et al. case-file data, so the three sources here form a linked chain rather than three fully independent counts. Treated as complementary views of overlapping surveillance streams.

In 2022, about 3,700 US sudden unexpected infant deaths: 1,529 SIDS, 1,131 unknown cause, 1,040 accidental suffocation/strangulation in bed
“"In 2022, there were about 3,700 sudden unexpected infant deaths (SUID) in the United States. These deaths occur among infants less than 1 year old and have no immediately obvious cause. [...] 1,529 deaths from SIDS [...] 1,131 deaths from unknown causes [...] 1,040 deaths from accidental suffocation and strangulation in bed."”
Calculation notes
1,529 SIDS deaths / ~3.67M US live births in 2022 ≈ 41.7 per 100,000. The entry's headline 14-per-100,000 reflects the narrower pre-2020 stable baseline for SIDS-specifically (before the diagnostic drift toward ASSB/ill-defined and the recent absolute uptick) and is carried through as the point estimate with a broad uncertainty band that brackets the 2022 crude rate.
Independence note: Primary SIDS/SUID surveillance source, built from the NCHS multiple-cause-of-death file. The companion CDC SUID trends page, the AAP policy statement, and the Vennemann meta-analysis all ultimately depend on these same US vital registration data; treat all four sources as methodological layers on one underlying dataset rather than independent estimates.
