Considering trends in global mobility - what does the future look like?

• 89% of organizations plan to increase their mobile workers in the next two years
• 80% of Millennials want to work outside their home country at some point during their career
• 71% of firms are actively searching for talent in different geographies, industries and demographics
• 78% of employers expect to see changes in the way their company manages talent in the near future
• 74% of mobility managers have reduced costs associated with international assignments directly in response to economic pressures
• 34% of employers report trouble filling key positions

These trends, pointed out by the "survey of surveys" done by CERC and EuRA, all add up to what would appear to be a very healthy outlook on global mobility volumes. However, most of us are concerned about a few things that could negatively impact global economies and therefore the movement of talent by companies.  

Here is a list of my top 5 concerns that could push against volume increases:

1. Global insecurity — includes terrorism and the  refugee crisis — raises the question of how will companies get people to move if their safety is in jeopardy?
2. The impact of Chinese economy on emerging markets — with the Chinese having invested huge amounts in Africa, Latin America and South Pacific, if their growth slows, how will this impact those emerging markets?
3. The final outcome from Brexit — too soon to say much more about this right now...we'll see!
4. The lack of leaders with a global mindset that seem to cave to political populism — right about now that seems to include most everyone
5. Environmental issues — the impact of pollution, changing weather patterns and catastrophic events, and the costs to counteract or deal with these.

From where you sit, would you say you are very optimistic about global mobility volumes increasing or expecting volumes to be quite negatively impacted by global forces?
