Data: CDC National ART Surveillance System (NASS). The "Over 40" column is the CDC's single above-40 bracket in the cumulative own-eggs table; CDC does not split 41-42 from 43+ in this dataset.
Colorado live-birth rates by CDC age band
The overall figure above blends every age together, which is why comparing clinics inside one band is the comparison worth making. Across Colorado's reporting clinics the youngest and oldest bands differ by 41.4 percentage points – age is the strongest single driver in this dataset.
| Age band | Colorado clinic mean | National clinic mean | Difference |
|---|---|---|---|
| Under 35 | 49.6%7 clinics publish this band | 48.0%399 clinics | +1.6 pts |
| 35 to 37 | 34.3%5 clinics publish this band | 35.3%358 clinics | -1.0 pts |
| 38 to 40 | 19.4%5 clinics publish this band | 22.5%355 clinics | -3.1 pts |
| Over 40 | 8.2%5 clinics publish this band | 8.8%303 clinics | -0.6 pts |
Each band is an unweighted mean of the clinics that publish it, which is why the clinic count differs by row – nationally 399 clinics report an under-35 rate and 303 report an over-40 one. Bands are not cycle-weighted, so a large clinic counts the same as a small one. A difference from the national mean reflects patient case mix as much as anything a clinic does, and is not a treatment recommendation: use it to choose which clinics to look at, then compare those clinics inside one band.
