Who Is Hosting This took a deep dive into the world of domain registrations and domain name renewal rates. They enlisted the services of Whois XML API, and put together their report.
From the article:
The Sample
Whois XML API collected data on one million domains registered on the most popular eight TLDs by the number of domain registrations. All are gTLDs apart from the ccTLD .CN (People’s Republic of China), but some might surprise you.
The randomly selected sample was made up of the following domains:
| TLD | Sample Size |
| .COM | 796,501 |
| .NET | 84,153 |
| .TOP | 53,691 |
| .ORG | 35,844 |
| .INFO | 17,655 |
| .CN | 7,111 |
| .XYZ | 3,840 |
| .BIZ | 1,205 |
Only 30% of domains registered are kept after one year
Over two in five domains are left to expire each year
28.99% of domains are re-registered by other users
