undefined To find the growth rate, follow these steps:

1. **Find the population change**: 
   - Current population = 12,000
   - Population in 2001 = 15,321
   - Change = Current population - Population in 2001
   - Change = 12,000 - 15,321 = -3,321

2. **Find the number of years**:
   - From 2001 to now (2023) = 2023 - 2001 = 22 years

3. **Calculate the growth rate** (as a decimal):
   - Growth rate = Change / Number of years
   - Growth rate = -3,321 / 22 = -151.86

4. **Convert to percentage**:
   - Growth rate in percentage = (Growth rate / Population in 2001) × 100
   - Growth rate in percentage = (-151.86 / 15,321) × 100 ≈ -0.99%

So, Tinseltown's growth rate is about -0.99%. This means the population is decreasing.

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

The following formula can be used to determine the rate of change or percentage change over time: #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) The result of solving the formula with these values substituted is: #p = (12000 - 15321)/15321 * 100# #p = (-3321)/15321 * 100# #p = (-332100)/15321# #p = (-332100)/15321# #p = -21.7#

undefined To calculate the growth rate, use the formula:

$$ \text{Growth Rate} = \left( \frac{\text{Current Population} - \text{Initial Population}}{\text{Initial Population}} \right) \times 100 $$

$$ \text{Growth Rate} = \left( \frac{12000 - 15321}{15321} \right) \times 100 $$

$$ \text{Growth Rate} = \left( \frac{-3321}{15321} \right) \times 100 $$

$$ \text{Growth Rate} ≈ -21.67\% $$

Therefore, the growth rate for Tinseltown's population is approximately -21.67%.
