May 2026 TIOBE Ranking: Statistical Languages Face Major Consolidation
The May 2026 TIOBE index shows Python and R emerging as the dominant forces in statistical programming, while legacy tools like MATLAB, SAS, and SPSS tumble, new entrants such as Stan and Zig gain traction, and the overall market undergoes a pronounced consolidation toward a few ecosystems.
May 2026 TIOBE Index – statistical programming languages
R reclaimed the 8th position, matching its all‑time best.
Decline of legacy statistical platforms
MATLAB is close to falling out of the top‑20.
SAS dropped out of the top‑30 for the first time.
Wolfram Mathematica’s popularity continues to fall.
SPSS fell out of the top‑100.
S language is near the top‑100 cutoff.
Stata is ranked 124.
The drop is attributed to shrinking ecosystems, diminishing developer communities, and missing AI‑era compatibility rather than functional shortcomings.
Julia’s market position
Despite performance comparable to C and strong mathematical capabilities, Julia has not entered the top‑30. The analysis cites ecosystem health, community size, corporate adoption, AI integration, tutorial availability, job demand, third‑party libraries and engineering compatibility as decisive factors.
Emerging languages
Stan is expected to appear in the index soon, reflecting growing interest in probabilistic programming and Bayesian methods for AI, healthcare, epidemiology and finance.
Zig is rapidly approaching the top‑30, offering near‑C performance, a modern toolchain, concise syntax and a lower learning curve, targeting lightweight high‑performance system development.
Traditional backend languages
Java and C++ swapped positions in the ranking, a change linked to the release of Java 26, indicating continued relevance for enterprise and government back‑ends.
Top‑10 languages (May 2026)
Python, C, Java, C++, C#, JavaScript, Visual Basic, R, SQL, Delphi/Object Pascal.
Market concentration
The statistical programming market is now dominated by two ecosystems:
Python serves as the universal interface for AI frameworks, machine‑learning libraries, data‑engineering tools and cloud production systems.
R remains essential for academic statistics, bio‑statistics, epidemiology and high‑level statistical analysis, supported by a mature package ecosystem built over two decades.
