Summary: A survey shows on the first glance that project managers in internal projects and in customer projects earn similar income on a global scale. However, digging deeper into the details, a surprising difference gets revealed

Note: The survey is currently repeated here.
The project is embedded inside the organization to bring about deliverables that the organization is interested in. Performing and receiving organization are the same legal entity.
Typically, Project managers in internal projects have the responsibility to manage cost centers.
Table 1: Income comparison, global numbers
We gathered data during a survey performed in May 2018. After clearing out responses that said that their project setting is different, and also obviously implausible responses, 275 responses were left for analysis, out of which 174 said that they were in customer projects, while 101 had reported that they managed internal projects.
On the first glance, there seemed to be no relevant difference between the income numbers reported by the two groups. The median numbers seemed to benefit internal projects, while for the average numbers, which are more accurate but also more sensitive to bias from outliers, customer projects seemed insignificantly ahead.
Overall, one can conclude that on a Global level, no significant difference could be found.
Digging deeper however showed a surprising pattern.
The picture is changing, when one relates the income numbers to the various regions from which the participants came. Table 2 shows the results for those regions from which at least 5 persons from both project types responded.
There seems to be a consistent picture: In high-paying regions like North America and the EU, project managers in customer projects reported higher payments. In medium and low paying regions, project managers in customer projects reported lower average income numbers than their colleagues in customer projects.
Table 2: Income comparison by regions
The numbers in Table 2 seem to reflect different expectations in world regions, when companies decide to procure project work:
The dominant driving force for the buyer seems to be the tapping into contractors’ assets, such as:
In order to make these resources available, customers have to pay a price high enough that it will make it worthwhile for the seller to become the contractor.
In such a situation, the Buy option is chosen mostly to get things done by thoroughly competent contractors. The higher salaries that these contractors pay reflect their expectations of future profits from the projects.
In the regions where project managers in customer projects earn less than internal project managers, a much stronger consideration seems to be the objective to get project work done cheaply. Here, the contractor must be cheaper than the customer's internal resources. The price pressure from the customer will then translate into lower earnings for the contractor’s staff, accepting that people will possibly work on the project with lower qualification and motivation.
In such a situation, the Buy option is chosen predominantly to get things done by cheap contractors. The lower salaries paid by these companies rather reflect their actual poor profitability and possibly also their poor liquidity.
The data above refer to gross salaries, i.e. the money paid by the employer. Participants were members of the social networks LinkedIn and Facebook, who communicated in their profiles and in group memberships that they worked as project managers.
The average income of project managers in customer projects was insignificantly higher than that
of their colleagues from internal projects. Comparing the median values of the
two groups instead, internal projects had the slightly better pay, as shown in
