Study details & methodology
| Name | “Children’s Online User Ages” Ofcom Children’s Online User Ages, Wave 2. |
| Country | “The sample for the survey was designed to be representative of UK internet users aged 8 to 17 years” |
| Publication year | “Published 8 May 2024” |
| Fieldwork dates | “22nd January-5th February 2024.” Fieldwork ran 22 January – 5 February 2024. |
| Sample size | “W1 8-12 (915), W2 8-12 (908)” The entry covers 908 respondents aged 8–12, within the full sample of 1,808 aged 8–17. Eligibility required an own profile on at least one listed app. Individual-app bases vary; the profile-age calculations use a smaller subset with a calculable user age. |
| Age range | “Male 8 to 12”“Female 8 to 12” The displayed entry uses the 8–12 age group in the unweighted sample profile. |
| Sampling | “The survey was conducted using the YouGov bespoke online survey platform.” Non-probability YouGov online panel; children recruited via parents/carers. Quotas aimed for at least 50 interviews per age group (8-12, 13-15, 16-17) per app/site. |
Harms measured
| Underage Use | “Q1. Which of the following apps and sites do you use?”“Q2. Below are the apps and sites you said you use. Some need a profile or account to be set up first.” Q1 records app use and Q2 distinguishes own profiles from borrowed profiles or no profile. Age combined with own-profile status supports the under-13 coverage here. Separate questions measure the date of birth supplied when the profile was created and whether age verification was requested; a misstated profile age is not itself the definition of underage use. |
Platforms measured
| Platform list | “Q1. Which of the following apps and sites do you use?” Own-profile and profile-age questions document 9 eligible apps for ages 8–12. YouTube is excluded because permitted supervised access is not distinguished. Low-base reporting limits do not remove documented measurement. |
Per-app measurement by harm
| Underage Use | “Q2. Below are the apps and sites you said you use. Some need a profile or account to be set up first.” Own-profile and profile-age questions document 9 eligible apps for ages 8–12. YouTube is excluded because permitted supervised access is not distinguished. Low-base reporting limits do not remove documented measurement. |
