Sinp'o is divided into 16 tong (neighbourhoods) and 6 ri (villages):
The average temperature is -4.1 ℃ in January and 22.6 ℃ in August. The average annual rainfall is 688 millimeters.
It is an important base for fishing, with a recent government emphasis on aquaculture. The DPRK has created aquacultural cooperatives and a central aquaculture office in the city.
Near Sinp'o in 1987 the building of first national nuclear plant was started by the USSR but construction was cancelled in 1991 due to lack of funding and in 1993 finally according to political reasons.
Later this place was the site of two planned reactors which were to have been built by the Korean Peninsula Energy Development Organization (KEDO) with international support. Preparations on site began in 1994 and construction of a reactor started in 1997, but was never completed. The last foreign workers were removed from the area in January 2006.

SINPO, acronym for signal, interference, noise, propagation, and overall, is a Signal Reporting Codes used to describe the quality of radio transmissions, especially in reception reports written by shortwave listeners. Each letter of the code stands for a specific factor of the signal, and each item is graded on a 1 to 5 scale (where 1 stands for nearly undetectable/severe/unusable and 5 for excellent/nil/extremely strong).
The code originated with the CCIR (a predecessor to the ITU-R) in 1951, and was widely used by BBC shortwave listeners to submit signal reports, with many going so far as to mail audio recordings to the BBC's offices. It has been expanded in some places to a SINPFEMO code which includes rating the station's modulation and other audio qualities, but the expanded code is rarely used in practice.
Both SINPO and SINPFEMO are the official signal reporting codes for international civil aviation.
The use of the SINPO code can be subjective and may vary from person to person. Not all shortwave listeners are conversant with the SINPO code and prefer using plain language instead.
