The population from 2001 until now has decrease by #21.7#%

The percentage change or rate of change over time can be calculated using the formula:

#p = (N - O)/O * 100#

Where:

#p# is the percentage change (what we are looking for)

#N# is the New Value (12,000)

#O# is the Old Value (15,321)

Substituting these values into the formula and solving gives:

#p = (12000 - 15321)/15321 * 100#

#p = (-3321)/15321 * 100#

#p = (-332100)/15321#

#p = -21.7#
