"Has statistics" does a lot of work here. When we weight visible dilapidation of the city against a set of figures showing some metric decreasing - a reasonable question would be how well this statistic reflects the reality on the ground. If we aggregate all crime over all the territory and get this metric to go down - does it mean we are doing great, or does it mean the crime became more concentrated in some places and now we have safe remote havens for the rich and a criminal hellscape for the less fortunate? Or does it mean we stopped reporting some things as "crime" either because the law does not care anymore or because citizens gave up on reporting it because it's useless anyway? I don't say it necessarily means that - I am just saying that you can not consider isolated metrics alone, you should always also consider how well these metrics reflect the underlying reality.
