On the basis of a survey conducted at the city skirt where floating population lives in compact communities，this report analyzed their status of employment. The analysis shows that the employment of the floating population is mainly in the area of relatively low-end commercial services；their income is comparatively low，with monthly balance varying with different age groups，labor security being insufficient and rate of participation in social insurance being low. The location of employment is largely at the city skirt and adjacent areas，and the labor intensity is relatively high. The main reason for working in Beijing is to achieve upward mobility. Their floating is more often than not supported by informal connections. There is difference between the older and the younger generation in terms of the desire of permanent residence，with the former being more desirous of stable employment.
