Question

Career in IT

On what resources, sites can you find out how things are in a particular
professional area?
For example, find out the current trends:

• increase or decrease in the number of vacancies
  
• rising or falling wages
  
• And so on
  

Examples ( these are just examples ):
In the graphic design industry (this is just an example, you can put any
field here) there is a drop in salaries due to the fact that the market is flooded
with housewives and hungry schoolchildren / students.
Or in the field of 3D modeling: there is such a trend that mostly
highly qualified specialists are required, and people with low and medium skills are engaged in
architectural visualization (also called "archive" - ​​this area is considered
unpromising and low-paid). That is, basically, even a strong average worker
cannot get a normal job as a 3D modeler, unlike other areas where
an "average worker" may well get a decent job.
Once again, the examples above are just examples . Trends in these
areas may currently be different .

Answer 1

I can answer for all areas at once: everyone thinks that they pay for working in IT, as a result, all IT began to be "flooded" by ignorant PR people.
And it is beneficial for employers: they emulate competition and reduce the salary of everyone in a row, including normal knowledgeable employees, referring to the fact that we will still find a cloud of people like you in your place and gradually weed out the ignorant, leaving the salary of good knowledgeable employees at the initial level.
As a result: the labor costs, education and experience of the applicants have become absolutely blurred in the IT labor market, which contributes to the elimination of "foreign" people from IT.
Real employees have turned into wanderers who do not want to face such things and who are looking for competent employers (who are willing to pay well for work and their experience) and a high-class team that was formed by the same employer to successfully run their business.
In any structure, at the time of its expansion, there are various vacancies for new employees with different experience and knowledge.
But, to a greater extent, the key role is played by the lack of education and lack of knowledge of the subject area of ​​the leaders of such new units themselves and the inability to correctly assess the potential of a candidate before being hired for specific tasks assigned to this unit.
And as a result, the one who did not cope with the task is always to blame, and not the one who allowed it.

Answer 2

naturally on ebanoe.it

Answer 3

The problem is that any IT industry is growing, even during a crisis, it’s just slower, and the number of specialists is not growing, since universities have been on vacation for the past decades, hence the constant increase in salaries in IT. Well, housewives and schoolchildren, and generally not competitors, it makes no sense to consider them

Answer 4

On the websites of headhunters - you look at the demand for specialists and analyze it.
Sometimes ready-made analytical articles are published by the same headhunters.

Answer 5

there are no such resources
(well, you can read all sorts of " salary surveys ")
(there is normal nationwide statistics only in the USA),
but you look at the problem from the wrong side: there is no absolute truth in "how things are", the employer or can sell your work, or there is no
vacancy - dozens of open ones hang, and if there is no demand for a narrow specialization in the city - there is no point in waiting, you need to change
either the specialization or the city

Both regularly publish research results and statistics by industry and region on demand / supply / salary.
Some of the statistics are in the public domain, some are for money (Zarplatomer magazine).
