Here we discuss some items relevant to the Pre-PIT Scan, as well as some initial planning for the sheltered and unsheltered counts
The below is a (not super beautiful) map of the Pre-PIT scan regions, symbolized by the number of individuals counted in during the 2024 count in each census tract for reference. Click on each region to get the count of individuals in each tract; you can also see the breakdown in the table below the map.
| subname | region_count | classification |
|---|---|---|
| CB1 | 168 | Very High |
| FS1 | 4 | Low |
| FS2 | 4 | Low |
| FS3 | 4 | Low |
| FS4 | 0 | Low |
| NE1 | 50 | High |
| NE2 | 40 | Medium |
| NE3 | 28 | Medium |
| NW1 | 0 | Low |
| NW2 | 38 | Medium |
| NW3 | 2 | Low |
| NW4 | 64 | High |
| S1 | 58 | High |
| S2 | 75 | High |
| S3 | 23 | Medium |
| S4 | 35 | Medium |
| W1 | 7 | Low |
| W2 | 51 | High |
| W3 | 128 | Very High |
We advise using Survey123 again for the Pre-PIT scan. Survey123 does not have an auto-populate option where a user can select a response at the beginning and continue to have it automatically filled in for subsequent responses. However, we advise exploring one of the following two methods:
Creating multiple surveys by breaking down the region shapefile
by outreach team. With this, we could use colors, big warnings on top,
etc., to make sure outreach teams are using the right survey.
*(Example: This survey is for the FEATHERFIST outreach team. If you are
not part of FEATHERFIST
Using radio buttons at the beginning of the survey, which only requires one click.
Sources for estimates for the 2024 count are included below.
| Source | Count |
|---|---|
| default_of_zero | 565 |
| hotspot_estimate_winter | 77 |
| manual_certainty | 19 |
| pre_pit_scan | 138 |
While at this point we obviously do not have all of those sources ready, the below shows what our classifications would be if we used manual certainty and unsheltered 2024 counts for classifications.
| Classification | Count |
|---|---|
| rare | 689 |
| certainty | 21 |
| medium | 82 |
| high | 8 |
With this breakdown, to keep the sampling the same as last year (85% of all medium tracts and 10.5% of all rare tracts) we would need to sample 171 tracts.
Note, however, that this is assuming we keep the manual certainty tracts the same as we did in 2024. The below map shows all of the manual certainty tracts from last year for DFSS review.
We have discussed adjusting sheltered count methodology so that shelters with more families are not underrepresented. To do this, we advise adjusting the percentage of heads of households surveys based on household size for each group. The average household size for individual adult households is just barely over 1, so for individual households the percent of hoh’s surveyed should remain at 10%, however, for households with adults and children this should be adjusted:
the average asylum seeking family has 3.6 members, so 36% of heads of households should be surveyed
the average non-asylum seeking family has 3.2 members, so 32% of heads of households should be surveyed
