Sometimes Google search result showed up charts from Statista. But does not that mean that Statista is a reliable source for those particular topical searches? Sometimes, I found issues with data from Statista. I do not know whether Statista has a proper vetting procedure. I hope it does.
Is Statista a reliable source for data?
Statista is a great starting point for any research. However, its charts do not show up the sources and require an account to see the data sources. For non-members, it makes the data seem coming out of the black box. Simply, you cannot trust the data without knowing the data source.
Remember Statista is a data aggregator and most of the time it shows up data from other sources. Those sources can be highly unreliable. So, need to do proper due diligence before using its data.
Most of the time, Statista would ask for upgrading the account to get accesses the data. Their customer service is quite notorious. I have personally gone through a very nasty process but at the end did not subscribe. For more details, you can see other people experiences here.
Most universities also trust Statista, and they have library accounts with Statista. This may be due to Statita past reputations. I am worried about the quality of research if students rely on Statista.
It was quite a reliable source a few years ago and was doing a stunning job by providing hard to find data. I was quite actively using it back in 2009. Probably at that time not that much data was available online.
But I think over the last 5-6 years, Statista started including those unreliable and low-quality data sources. This has hit Statista reputation as well. I think it is time for Statista to be more serious about quality rather than quantity. It can use all those AI and vetting tools to make sure that it provides data from highly reputable and reliable sources.
I would suggest http://www.knowtraces.com for industry-related data. We provide market assessments and forecasts covering industries such as construction, packaging, automotive, telecom, metals etc.
