The Baltic States are facing significant demographic and economic challenges that may necessitate a consolidation of their defense forces and a greater inclusion of women in military roles.

In recent years, the military landscape in Estonia, Latvia, and Lithuania has seen a notable revival, with defense spending reaching unprecedented levels. Defense ministers have been actively engaged in unveiling new weapon systems and announcing substantial funding packages.
However, experts warn that the current design of the defense system requires foresight; failing to plan for the next decade could lead to a sudden resource crisis in national defense. Estonian security analyst Meelis Oidsalu emphasizes the urgency of this situation.
A key area for consideration is enhancing defense cooperation among the Baltic States. This could involve joint development of military capabilities, the establishment of unified branches of armed forces—such as naval and air units—and auxiliary services including logistics, intelligence, communications, and procurement.
From NATO’s perspective, the Baltic States function as a single military defense operation during wartime, with no separate defense plans for Estonia, Latvia, or Lithuania. While the idea of creating joint defense forces may raise concerns about national sovereignty, it is noteworthy that airspace security for these countries is already provided by foreign aircraft.
UN forecasts indicate that if current demographic trends and immigration policies continue, the population of the Baltic States could decline by 3.1 million people by the end of the century. Latvia’s population may fall below one million, while Lithuania could see its population shrink to levels comparable to Estonia’s today. Nearly half of this population decline is expected to occur by 2054, a timeline that poses immediate concerns given the slow pace of military development.
As of 2022, the median age in Estonia was 42 years, while Latvians and Lithuanians had a median age of 43. Projections suggest that by the end of the century, these figures could rise above 50 years, with Lithuania potentially having an average age of 52.6 years—among the highest in Europe.
The economic downturn also poses a challenge to defense budgets alongside the declining population. If growth rates do not improve, immigration does not increase significantly, and gaps are not filled by advancements in robotics and technology, the Baltic States may find themselves with defense forces that are one-fifth smaller over the next three decades. Staffing these forces will likely become increasingly difficult under such circumstances.
