We study the hierarchical stellar structures in a \sim 1.5 deg ^ { 2 } area covering the 30 Doradus-N158-N159-N160 star-forming complex with the VISTA Survey of the Magellanic Clouds .
Based on the young upper main-sequence stars , we find that the surface densities cover a wide range of values , from log ( \Sigma \cdot pc ^ { 2 } ) \lesssim - 2.0 to log ( \Sigma \cdot pc ^ { 2 } ) \gtrsim 0.0 .
Their distributions are highly non-uniform , showing groups that frequently have sub-groups inside .
The sizes of the stellar groups do not exhibit characteristic values , and range continuously from several parsecs to more than 100 pc ; the cumulative size distribution can be well described by a single power law , with the power-law index indicating a projected fractal dimension D _ { 2 } = 1.6 \pm 0.3 .
We suggest that the phenomena revealed here support a scenario of hierarchical star formation .
Comparisons with other star-forming regions and galaxies are also discussed .
