I have no problem doing research, I just know that there are no officially viable numbers available anywhere. A sample size of 2,000 people is nothing compared to the install base of iOS. I think the only numbers we can take at face value are those that are presented by Apple, which they haven't done for this cycle yet.
iOS 18 Installed on 76% of iPhones Introduced in the Last Four Years
iOS 18 adoption is on pace with iOS 17 adoption last year, according to iOS 18 adoption statistics provided by Apple. iOS 18 is installed on 76 percent of iPhones introduced in the last four years, while 63 percent of iPads from the last four years are running iPadOS 18. 68 percent of all...
And why have they not provided numbers? They did last year for iOS 18. January is already passed.

Also, you're just wrong
A sample size of
2,000 people is often considered the "gold standard" for large-scale research because it offers high precision with manageable costs. In a population of millions, this sample size provides a very reliable snapshot of the whole.
Key Metrics for a Sample of 2,000
- Margin of Error: Typically ±2.1% or ±2.2% at a 95% confidence level. This is significantly more precise than the ±3% margin standard in samples of 1,000.
- Confidence Level: Most studies use a 95% confidence level, meaning if you ran the survey 100 times, 95 of those times the results would stay within that ±2% margin.
- Statistical Power: A sample of 2,000 provides high statistical power (often exceeding the 80% industry benchmark), making it highly likely to detect small but real differences between groups.
Again do some basic research. You're so invested in this subject but can't bring yourself to look at anything other than what I spoon feed you.
