  We review cosmological inference from optical and radio galaxy surveys, the
X-Ray Background and the Cosmic Microwave Background. We focus on three topics:
(i) First results from the 2dF galaxy redshift survey; (ii) Estimation of
cosmological parameters by joint analysis of redshift surveys and CMB data; and
(iii) The validity of the Cosmological Principle, and constraints on the
fractal dimension on large scales.
