  We trace the star formation regions in the SMC and study their properties.
The size and spatial distribution of these regions is found to support the
hierarchical scenario of star formation, whereas, the evaluation of their
intensity, contributes to the understanding of the various stages of star
formation. Their connection to the LMC-SMC close encounter, about $(0.9-2)
\times 10^{8}$ years ago, is investigated as well. The SMC, being almost
edge-on, does not easily reveal these areas, as is the case with the LMC.
However, a study through multi-wavelength images such as optical, IR and radio
has been proved very useful. A selection of areas, with enhanced 60 and
100-$\mu$m infrared flux and emission in all IRAS bands, identifies the star
forming regions. All of the identified regions are dominated by early-type
stars and considering their overall size (increasing order) a total of 24
aggregates, 23 complexes, and 3 super-complexes were found. We present their
coordinates, dimensions, and IR fluxes. Moreover, we correlate their positions
with known associations, SNRs, and \hii regions and discuss their activity.
