The annual_relocation_rates_for_households table

The annual relocation rates for households, by combination of age and income of household. These values are the probabilities that a household with the given characteristics will relocate within the time span of one year. They do not alter from year to year. This table is only used by the Household Relocation Choice Model.

Column Name	Data Type	Description
age_min	integer	The minimum age for which this probability is valid.
age_max	integer	The maximum age for which this probability is valid, -1 means no maximum
income_min	integer	The minimum income for which this probability is valid.
income_max	integer	The maximum income for which this probability is valid, -1 means no maximum
probability_of_relocating	float	The probability of relocating in a year.

• age_min must be >= 0
• age_max must be > age_min or else -1
• incomde_min must be >= 0 and must be a multiple of 1000.
• income_max must be > incomde_min and a multiple of 1000 -1 (e.g. 200,999) or else -1
• probability_of_relocating must be >= 0.0 and <= 1.0
• The ranges must be disjoint and cover the entire space (from zero to infinity in the two-dimensional space produced by age and income).

As an example, this table:

age_min	age_max	income_min	income_max	probability_of_relocating
0	2	0	4999	0.5
3	-1	0	3999	0.6
0	-1	5000	-1	0.7
3	-1	4000	4999	0.9

Would produce a space like this:
