We present XMM-Newton spectral analysis of all 38 Seyfert galaxies from thePalomar spectroscopic sample of galaxies. These are found at distances of up to67 Mpc and cover the absorbed 2-10 keV luminosity range ~10^38-10^43 ergs/s.Our aim is to determine the distribution of the X-ray absorption in the localUniverse. Three of these are Compton-thick with column densities just above10^24 cm^-2 and high equivalent width FeKa lines (>700 eV). Five more sourceshave low values of the X-ray to [OIII] flux ratio suggesting that they could beassociated with obscured nuclei. Their individual spectra show neither highabsorbing columns nor flat spectral indices. However, their stacked spectrumreveals an absorbing column density of N_H~10^23 cm^-2. Therefore the fractionof absorbed sources (>10^22 cm^-2 could be as high as 55+/-12%. A number ofSeyfert-2 appear to host unabsorbed nuclei. These are associated withlow-luminosity sources Lx < 3x10^41 ergs/s. Their stacked spectrum again showsno absorption while inspection of the \chandra images, where available, showsthat contamination from nearby sources does not affect the {\it XMM-Newton}spectra in most cases. Nevertheless, such low luminosity sources are notcontributing significantly to the X-ray background flux. When we consider onlythe brighter, $>10^{41}$ \lunits, 21 sources, we find that the fraction ofabsorbed nuclei rises to $75\pm19 $ % while that of Compton-thick sources to15-20%. The fraction of Compton-thick AGN is lower than that predicted by theX-ray background synthesis model in the same luminosity and redshift range.}
