The question asks to identify the number of children that occurred the least frequently and to calculate the percentage of this occurrence.

### Step 1: Identify the least frequent occurrence
From the table:
- 0 children: 250 occurrences
- 1 child: 112 occurrences
- 2 children: 560 occurrences
- 3 children: 201 occurrences
- 4 children: 68 occurrences
- 5 or more children: 59 occurrences

The least frequent number is "5 or more" children with 59 occurrences.

### Step 2: Calculate the percentage
To find the percentage, use the formula:

\[
\text{Percentage} = \left( \frac{\text{Frequency of least occurrence}}{\text{Total frequency}} \right) \times 100
\]

Calculating the total frequency:

\[
250 + 112 + 560 + 201 + 68 + 59 = 1250
\]

So, the percentage is:

\[
\text{Percentage} = \left( \frac{59}{1250} \right) \times 100 \approx 4.72\%
\]

Hence, the correct answer is: **5 or more, 4.72%**.
