Is the amount of social security paid by each city uniform?

Social security includes employee social security, flexible employment social security, urban and rural residents social security and so on. In terms of local payment, the upper and lower limits of the payment base in the first two years are calculated according to a certain proportion of the local social wage in the previous year, and the social wage is different in different places and years, so the highest/lowest payment base in different places and years is different. In terms of social security for urban and rural residents, although there is no problem with the payment base, the state has not solidified the amount of individual contributions, so it varies from place to place.
