Counting Users 2012 extended

Extended version of the User Survey

Thanks to the help from colleagues at the US neutron and photon sources, the Photon and Neutron science user survey now also includes users from the US facilities! For limitations and details of the survey please spend a minute reading through the page explaining the user counting procedure.
These are the current results of the 2012 user survey. Latest update: Aug. 21th 2014.



Current status of the user survey:

The table shows the number of the hashes received and the number of unique entries. Duplicates have been filtered out, which results in the difference between number of users and hashes. Numbers in brackets are for the individual photon/neutron sources in cases where sites operate more than a single source.

How to interpret the numbers?
The table shows the number of common user between individual facilities as well as between Lightsources (photon) and Neutronsources (neutron). For example, the ESRF lists 10287 active users. 433 of the ESRF users are also known as active users at ELETTRA. A total of 1313 ESRF users are also active users at at least one of the Neutronsources as shown in the row labelled neutron.

The last three rows show some numbers for all unique Neutronsource users; all unique Lightsource users; all unique users. For example we count 10023 Neutronsource users in total (last column), 25336 Lightsource users and 33025 users alltogether. There are 2334 unique users which use both Lightsources and Neutronsources. Remarkably, there is not a single pair of facilities without common users.

Where do our users come from?

Currently we count users with home institutions located in 82 different countries, including places like New Caledonia or Botswana.
 

 
 
There is only a small number of countries without any scientists registered at any of the neutron or photon sites.
 

 

Yet another human development index?

Comparing the Human Development Index with the location of the users of the neutron and photon sources reveals an amazingly similar pattern
 

 

How often do users show up at the facilities?

Some users visit several facilites more than 30 times within 2 years, but the vast majority of our users show up at most twice in a 2 year time span. They are still using our services, submit proposals, access data or simply collaborate. This strongly emphaiszes the need for an advanced identity management and remotely accessible services of all kind. Roughly 1/3 of the users are first time users. Though results are still preliminary, that would indicate an increase of user in the order of 10.000 per year. To estimate the increase of active users more data are needed.

 

Gender and Age of our users

Roughly 30% of the users (with uniquely known gender) of the neutron and photon facilities are women, but for young scientists the ratio of female scientists is significantly higher. For 13% of the users the gender has not been recorded or could not be revealed, and roughly 5% appear as males in some databases and females in some others. The vast majority of the users are 40 years old or younger.
