  The spatial distribution of sources of gamma-ray bursts (GRB) with known red
shifts is analyzed by the conditional density and pairwise distance methods.
The sample of GRB is based on data from the Swift mission and contains fluxes,
coordinates, and red shifts for 384 GRB sources. Selection effects that distort
the true source distribution are taken into account by comparing the observed
distribution with fractal and uniform model catalogs. The Malmqvist effect is
modeled using an approximation for the visible luminosity function of the GRB.
The case of absorption in the galactic plane is also examined.This approach
makes it possible to study the spatial structure of the entire sample at one
time without artificial truncations. The estimated fractal dimensionality is
$D=2.55\pm0.06$ on scales of $2\div6$ Gpc.
