  The Tor Network has been a significant part of the Internet for years. Tor
was originally started in the Naval Research Laboratory for anonymous Internet
browsing and Internet-based communication. From being used for anonymous
communications, it has now segmented into various other use-cases like
censorship circumvention, performing illegal activities, etc. In this paper, we
perform empirical measurements on the Tor network to analyze the trends in Tor
over the years. We gather our measurements data through our measurement
scripts, past research in this domain, and aggregated data provided by the Tor
metrics directory. We use this data to analyze trends and understand the
incidents that caused fluctuations in the trends of different data parameters.
We collect measurements data for Tor parameters like Tor users, onion services,
Tor relays, and bridges, etc. We also study censorshiprelated events and study
trends by analyzing censorship-related metrics. Finally, we touch upon the
location diversity in Tor and study how the Tor circuit selection and
construction are impacted by the bandwidth distribution of Tor relays across
geographies.
