| It seems to be much worse in the US for now, though why is the subject of a great deal of speculation. There's not much publicly-available research on the topic. One better source I've found is "Robocalls: A Worldwide or US-only Problem? Analyzing Spam and Fraud in International Phone Calls" (30 Jun 2026) <https://arxiv.org/html/2606.31790> On the magnitude in the US vs. elsewhere: Even though robocalls are an international problem, our findings indicate that US citizens are substantially more affected than the rest of the world. The median number of phone numbers in our US honeypot was 11 751, compared to 101 913 international phone numbers. Despite an almost tenfold difference in the number of available phone lines, the US honeypot numbers received 8 314 813 calls (95.1%) compared to 432 538 calls (4.9%) received by the international numbers. On average, a single phone number in our US honeypot received 707.5 calls during a nine-month period, about 2.62 calls per day. Non-US numbers received, on average 4.24 calls during the same period, about 0.016 calls per day. The paper does not break out calls per person by country, though it discusses general patterns. Hiya has an accessible report which highlights "seven key countries", with calls per month in parenthesis: The US (22), UK (5), Canada (6), Spain (13), France (18), Germany (3), and Brazil (29, highest in the world). Americas: Brazil (29), Mexico (26), Chile (23), and the US (22) lead. In Asia: HK (23), Indonesia (16), the Philippines (12), and India (8) lead. <https://work.hiya.com/hubfs/2025/Global%20Call%20Threat%20Re...> |
