# Recent Data Import (2022-Present)
Quick, lightweight import for current/recent parliamentary data without bulk downloads.
---
## ๐ฏ Overview
Instead of importing 30+ years of historical data, this imports only recent data (2022-present) using the API directly.
### Advantages
โ
**No PostgreSQL needed** - Direct API to Neo4j
โ
**Fast** - Completes in 15-20 minutes
โ
**Small** - Only ~3 GB disk space
โ
**Current** - All MPs, bills, committees
โ
**Recent** - 3 years of debates/votes
### What You Get
- **All current MPs** (343)
- **All current bills** (111 from LEGISinfo)
- **Debates since 2022** (~300-500 sittings)
- **Statements since 2022** (~50,000 speeches)
- **Votes since 2022** (~500 votes)
- **All committees** (~25 active)
- **Recent expenses** (2023-present)
---
## ๐ Quick Start
### Prerequisites
- โ
Neo4j running (you already have this)
- โ
Python environment (you already have this)
- โ
No PostgreSQL needed!
### Run Import
```bash
python test_recent_import.py
```
**That's it!** No setup, no downloads, no PostgreSQL.

## ๐ Size Comparison
| Approach | Disk Space | Time | Data Range |
|----------|-----------|------|------------|
| **Recent Import** | 3 GB | 20 min | 2022-present |
| **Modern Bulk** | 40 GB | 60 min | 1994-present |
| **Complete History** | 100 GB | 2-3 hours | 1901-present |
---
## โ๏ธ Customization
### Change Date Range
Edit `test_recent_import.py`:
```python
importer = RecentDataImporter(
neo4j,
start_date="2020-01-01" # Change this!
)
```
**Options**:
- `"2024-01-01"` - Only this year (~5 min)
- `"2022-01-01"` - Last 3 years (~20 min, recommended)
- `"2020-01-01"` - Last 5 years (~40 min)
- `"2015-01-01"` - Last 10 years (~80 min)
**Rule of thumb**: Each year โ 100-150 debates, 15,000 statements, 6-7 minutes
### Skip Components
Edit `recent_import.py` to comment out what you don't need:
```python
# stats["debates"] = self.import_recent_debates(batch_size) # Skip debates
# stats["votes"] = self.import_recent_votes(batch_size) # Skip votes
```
---
## ๐ Data Volume by Year
| Year | Debates | Statements | Votes | Size |
|------|---------|------------|-------|------|
| 2024 | ~100 | ~12,000 | ~150 | ~500 MB |
| 2023 | ~150 | ~18,000 | ~200 | ~750 MB |
| 2022 | ~120 | ~14,000 | ~180 | ~600 MB |
| **Total 2022-present** | **~370** | **~44,000** | **~530** | **~2 GB** |
Add MPs, bills, committees: **+500 MB**
Add expenses: **+200 MB**
Add indexes: **+300 MB**
**Total: ~3 GB**

## ๐ What's Missing vs Bulk Import
### You Get
- โ
All current MPs
- โ
All current bills
- โ
All committees
- โ
Recent debates (2022+)
- โ
Recent votes (2022+)
- โ
Current expenses
### You Don't Get
- โ Historical MPs (pre-2022)
- โ Historical debates (pre-2022)
- โ Historical bills (pre-2022)
- โ Historical votes (pre-2022)
**But**: For most use cases (current affairs, MP tracking, recent legislation), 2022-present is sufficient!
---
## ๐ก When to Use Each Approach
### Use Recent Import If:
- Building a current affairs app
- Tracking current MPs/bills
- Prototyping/testing
- Limited disk space
- Need it working quickly
### Use Bulk Import If:
- Need historical analysis
- Academic research
- Long-term trends
- "What did MPs say in 2005?"
- Complete legislative history
### Use Both If:
- Start with recent (quick setup)
- Add bulk later (when needed)
- They work together seamlessly!
---
## ๐ฎ Example Usage
### After Import
```cypher
// Check what you have
MATCH (d:Debate)
WHERE d.date >= '2022-01-01'
RETURN count(d) AS recent_debates
// Find MP speeches in 2024
MATCH (m:MP)-[:SPOKE]->(s:Statement)-[:IN_DEBATE]->(d:Debate)
WHERE d.date >= '2024-01-01'
RETURN m.name, count(s) AS speeches_2024
ORDER BY speeches_2024 DESC
LIMIT 10
// Committee activity
MATCH (c:Committee)<-[:MEMBER_OF]-(m:MP)
RETURN c.name, count(m) AS members
ORDER BY members DESC
// Recent bills
MATCH (b:Bill)
WHERE b.session = '45-1'
RETURN b.number, b.title, b.status
ORDER BY b.number
```
---
## ๐ Incremental Updates
After initial import, run weekly/monthly to stay current:
```bash
# Update script
python test_recent_import.py
```
**What it does**:
- Fetches new debates since last run
- Adds new bills
- Updates MP info
- Merges (no duplicates)
**Time**: 2-5 minutes for weekly update
---
## ๐งน Cleanup
If you want to reset and re-import:
```cypher
// Delete recent data only
MATCH (d:Debate)
WHERE d.date >= '2022-01-01'
DETACH DELETE d
// Or delete everything
MATCH (n)
DETACH DELETE n
```
Then re-run import.

## โก Performance
### Import Speed
- MPs: ~30 seconds (343 records)
- Bills: ~2 seconds (111 records)
- Debates: ~10-12 minutes (300-500 debates)
- Votes: ~3-4 minutes (500 votes)
- Committees: ~10 seconds (25 records)
**Total: 15-20 minutes**
### Query Performance
Same as bulk import - fully indexed and optimized.
---
## ๐ฏ Bottom Line
**Recent import is the recommended starting point** for most users:
- โ
Fast setup (20 min vs 2-3 hours)
- โ
Small footprint (3 GB vs 100 GB)
- โ
No PostgreSQL needed
- โ
Covers all current/recent data
- โ
Can add historical later if needed
**Run it now**:
```bash
python test_recent_import.py
```
You'll have a working system in 20 minutes! ๐
